Duckling Hand-Rearing Guide | Feeding & Care

Hand Rearing Guide for Ducklings

Introduction: Ideally, ducklings should be raised by their mother or a licensed wildlife rehabilitator, as this provides the best nutrition, warmth, and behavioural development. But emergencies happen, and sometimes you're the only one who can help.

This manual is here to guide you through the essentials of hand-rearing a baby duckling with care and confidence. Whether you've found a lone duckling or are stepping in temporarily, you’ll find practical advice to help give it the best possible start.

DISCLAIMER: This is a basic guide and doesn’t cover every issue that can arise when hand-rearing ducklings. It’s based on what’s worked best for us through experience and research. If you have any questions, feel free to email, we’re happy to help.

Set Up Checklist

Brooder Setup

Brooder setups can take many forms, from purpose-built brooders and incubators to simple DIY setups using materials you already have. Below are a few common options, but there’s no single correct setup. The important thing is creating a safe, warm and comfortable environment that meets the ducklings’ needs.

Cleaning Supplies

Cleanliness is essential when raising ducklings. Keep paper towels, mild dish soap, white vinegar and a bird-safe disinfectant such as F10 on hand. Wash food and water bowls thoroughly every day, clean up spills and droppings as needed, and replace soiled or damp bedding frequently. Ducklings are notoriously messy, so keeping their environment clean and dry helps reduce bacterial build-up and disease risk.

Digital Thermometer

A thermometer is essential for monitoring the temperature inside your duckling brooder, particularly during the first few weeks when young ducklings are not yet able to regulate their body temperature effectively.

Place the thermometer at duckling level, rather than higher up in the brooder, so it reflects the temperature they are actually experiencing. Ideally, monitor both the warm and cooler areas of the brooder.

Temperature provides a useful guide, but always watch the ducklings as well. Huddling tightly together or constantly seeking the heat source can indicate they are too cold, while spreading out, panting or avoiding the heated area may mean they are too hot.

Enrichment & Companionship

Enrichment is an important part of raising healthy, well-adjusted ducklings. Mirrors and soft toys can be particularly helpful for ducklings being raised alone, providing comfort, stimulation and a sense of companionship.

However, we do not recommend raising a duckling alone where this can be avoided. Ducks are highly social birds, and another duckling provides companionship and social interaction that toys and mirrors cannot fully replace. Where possible, connect with other rehabilitators, fosterers or people caring for ducklings to find suitable companions of a similar age and size.

Other simple enrichment options include safe objects to investigate, supervised foraging opportunities, shallow water play when appropriate, and plenty of space to explore.

Food Supplies

Duckling starter crumble: A quality commercial duckling or waterfowl starter crumble should form the foundation of the diet. Choose an appropriate unmedicated feed.

Unmedicated chick starter crumble: A practical alternative when duck-specific feed is unavailable. Additional attention may need to be given to niacin levels, as ducklings have higher requirements than chicks.
Brewer’s yeast: Can be added to the diet as a supplementary source of B vitamins, particularly niacin.
Bird-specific multivitamin: Useful for providing additional vitamin and mineral support where the diet may be inadequate or during periods of increased nutritional demand.
Fresh greens: Finely chopped leafy greens, grasses and other suitable vegetation can be introduced from an early age alongside their main diet.
Grit: Fine, appropriately sized grit should be provided once ducklings are eating greens, insects or other foods that require grinding in the gizzard.
Unmedicated grower pellets or crumble: As ducklings mature, they should transition from starter crumble onto an appropriate duck, waterfowl or poultry grower feed.
Treats and supplementary foods: Insects, peas and other suitable foods can provide enrichment and dietary variety, but should remain a small part of the diet rather than replacing a balanced commercial feed.

Food & Water Conatiners

Choosing the right food and water containers helps keep ducklings clean, dry and healthy. Shallow dishes or small poultry feeders work well for food and should be stable enough that they cannot easily be tipped over.

Water containers should allow ducklings to fully dunk their bills and clear their nostrils, while limiting their ability to climb into the water and become wet or chilled. Gravity-fed poultry waterers are a good option, as they help reduce spills and keep drinking water cleaner.

Ducklings are naturally messy around water, so place waterers on an absorbent or easy-to-clean surface and change wet bedding frequently. Wash food and water containers daily, and provide fresh drinking water throughout the day.

Heat Source

There are several ways to provide warmth for ducklings, and each has its own advantages and limitations. The best option will depend on the ducklings’ age, condition, number and the equipment you have available.

Plant propagation heat mats or plates: An affordable and readily available option. They provide gentle, consistent heat and work particularly well underneath or alongside part of the brooder. Always ensure ducklings can move away from the heated area.
SnuggleSafe heat discs: Useful for temporary setups, transport, overnight emergencies or situations where electricity is unavailable. They retain heat for several hours but gradually cool, so they need to be checked and reheated regularly.
Incubators: One of the best options for very young, chilled, weak or compromised ducklings because temperature can be controlled precisely and the environment remains stable. Good ventilation and regular cleaning are essential.
Wheat bags: Handy as a short-term or emergency heat source. Wrap them in a towel or other protective layer and check the temperature carefully, as they can develop hot spots and cool relatively quickly.
Hot water bottles: Another useful temporary option. Wrap well to prevent direct contact with hot surfaces and replace the water as it cools. Make sure they cannot leak into the brooder.
Heat lamps: Effective for heating a larger brooder and allowing ducklings to choose their preferred distance from the heat. However, they can overheat or dehydrate ducklings, dry the environment, and pose a fire or burn risk if poorly positioned or secured.

Whatever heat source you use, always create a temperature gradient. Heat only part of the brooder so ducklings can move towards warmth when cold and away from it when they become too hot. Their behaviour is one of the best indicators of whether the setup is comfortable.

Small Kitchen Scales

Accurate digital kitchen scales are essential for monitoring a duckling’s weight and growth throughout rehabilitation. Weigh your ducklings at approximately the same time each day so that changes can be compared accurately.

Regular weighing allows you to track growth and quickly identify weight loss, failure to gain weight or unexpected changes, which can be an early indication that something isn’t right. For very small ducklings, scales that measure in 1 g increments are ideal.

Brooder Set Up

Temperature: Start with a warm zone of 32 to 35°C (90 to 95°F) during the first week, reducing by around 3°C each week as ducklings grow and feather. Always provide a temperature gradient so they can move towards or away from the heat. Use a thermometer at duckling level and monitor their behaviour.
Bedding: Choose bedding that is absorbent, non-slip and easy to replace. Puppy pads, towels, paper towels and wood shavings can all work. Avoid loose or fraying fabric, as ducklings may pick at and swallow threads or become tangled in them.
Space: Ducklings grow quickly, so expect to upgrade their setup several times. Provide enough room to move comfortably, access food and water, and move between warmer and cooler areas.
Easy to clean: Keep the setup simple. Ducklings are exceptionally messy, particularly around water, so wet bedding, spilled food and droppings will need to be removed frequently.
Safety: Check for gaps, loose threads, sharp edges, exposed cords, unstable bowls and small objects. Keep electrical components away from water and remember that growing ducklings quickly become capable of climbing and escaping.

Brooder Option Ideas

Plastic storage container: Good first brooder, Easy to clean, cut air holes or add a mesh insert.
Pet Carrier Foldable: A good-sized, portable option, although fabric surfaces can make it more difficult to clean and disinfect.
Structured Play Pen: A good all round pen with plenty of space for development. You can also cut the bottom out if needed.
Fold Up Crate: The bottom of the crate can be removed, making it easy to transition the ducklings into an outdoor pen as they grow.
Collapsible Pen: Great for transitioning ducklings outdoors. Use alongside a warm, sheltered area.

Duckling Diet

+ Drinking Water

Ducklings should always have access to fresh, clean drinking water.

Depth: Deep enough to fully submerge their bills and clear their nostrils.
Safety: Avoid containers they can climb into and become soaked or chilled.
Cleanliness: Ducklings dirty their water quickly, so change it several times a day as needed.
Waterers: Gravity-fed waterers can help reduce spills and keep water cleaner for longer.
Placement: Keep drinking water close to food so ducklings can easily drink while eating.

+ Commercial Diet (Week 1 - 3)

Note: For Paradise ducklings go straight to week 3 diet

Chick starter crumble or mash, non-medicated
Sharps Duck Starter Crumble
NRM Game Bird Crumble
Westons Game & Quail Crumble

Feeding notes: Feed ad lib, with food available throughout the day. If using chick starter, provide additional niacin (brewer’s yeast or nutritional yeast) to help meet the higher requirements of growing ducklings.

Fresh foods: From around one week, small amounts of finely chopped leafy greens, grass, dandelion, duckweed, peas and other suitable vegetation can be offered for nutrition, variety and natural foraging enrichment.

+ Commercial Diet (Week 3 onwards)

Note: Paradise ducklings can start from here

Weston Milling Chook Grow Pellets
NRM Pullet Grower Pellets
MainFeeds Chick Grower
Passwell Crumbles
Chicken grower pellets, non-medicated
Chicken grower crumble, non-medicated

Feeding notes: Transition onto an appropriate grower diet from around three weeks. Make dietary changes gradually over several days. Continue additional niacin (brewer’s yeast or nutritional yeast) where the chosen feed does not provide adequate levels for ducks.

Fresh foods & enrichment: Continue offering a variety of greens, grasses, aquatic plants, vegetables and appropriate insects alongside the formulated diet. These should supplement, rather than replace, the nutritionally balanced commercial feed.

Avoid layer feed: Layer feeds contain calcium levels designed for actively laying birds and are not appropriate for growing ducklings.

+ Supplemental Extras

A quality duckling starter should make up the majority of the diet. The following extras can provide variety, enrichment and additional nutritional support as ducklings grow.

Fresh Greens, from 1 week

Small amounts of finely chopped greens and vegetables can be introduced from around one week of age. Good options include:

Dandelion greens
Silverbeet
Cos lettuce
Peas
Grated courgette
Grated carrot
Duckweed

Introduce new foods gradually and monitor droppings. Provide appropriate grit once foods other than crumble are being eaten.

Multivitamins

A bird-specific multivitamin can provide additional nutritional support during rapid growth, particularly when ducklings are being raised on a basic chick starter rather than a complete duckling feed. Avoid routinely combining multiple vitamin supplements, as more is not necessarily better.

Nutritional or Brewer’s Yeast

Nutritional or brewer’s yeast can provide additional B vitamins, including niacin, which is particularly important for growing ducklings. It can be mixed through dry crumble or sprinkled over slightly moistened feed.

If you want to give a specific mixing rate such as 1 tablespoon per cup, I would make sure it is based on the actual niacin content of the yeast you recommend. Niacin concentrations vary considerably between products, so a blanket tablespoon measurement may not reliably provide the intended amount.

Insects

Insects provide protein, enrichment and an opportunity for natural foraging behaviour. Suitable options include black soldier fly larvae, crickets, silkworms and small amounts of mealworms.

Offer insects as a supplement rather than a major part of the diet. Mealworms in particular are relatively high in fat and have an unfavourable calcium-to-phosphorus ratio, so they are best offered in moderation rather than as a primary protein source.

+ Important

Keep food close to water: Ducklings need ready access to water while eating so they can moisten and swallow their food and clear their bills and nostrils.
Wet feed: Crumble can be lightly moistened to make a soft mash. Only prepare small amounts and remove leftovers regularly, as wet feed can spoil or ferment quickly, particularly in warm conditions.
Avoid layer feed: Layer feeds contain calcium levels designed for laying birds and are not suitable for growing ducklings.
Limit scratch mixes: Mixed grains and scratch feeds are not nutritionally complete and should only make up a very small proportion of the diet.

Short-Term Homemade Diet

This recipe is intended as a temporary feeding option when a suitable commercial duckling feed is unavailable. It can help bridge the gap for a few days, but it is not nutritionally complete and should not be used as a long-term rearing diet.

Growing ducklings have specific requirements for protein, amino acids, vitamins and minerals that are difficult to reliably meet with a homemade mixture. Move onto a nutritionally balanced duckling or appropriate poultry starter/grower feed as soon as possible.

Recipe

1 part quick rolled oats
1 part finely mashed boiled egg, including yolk and white
½ part defrosted, mashed peas

Mix thoroughly and offer fresh.

Recommended Optional Additions

Nutritional or brewer’s yeast, for additional B vitamins, including niacin
Finely chopped greens, such as dandelion or silverbeet
Bird-specific multivitamin, used according to directions

Important: Prepare only small amounts at a time. Egg and other moist ingredients can spoil quickly, particularly in a warm brooder, so discard uneaten food regularly and thoroughly clean feeding dishes between batches.

Swimming

Ducklings can begin short, supervised swims from around one week of age, using lukewarm water at approximately 28 to 32°C.

Keep it brief: Start with short sessions and gradually increase swim time as they grow.
Supervise: Never leave young ducklings unattended in water.
Easy exit: Use a shallow container with a safe, easy way for ducklings to get in and out.
Warm up afterwards: Return ducklings to a warm, dry area where they can dry, rest and preen. Young ducklings can chill quickly after swimming.
Watch the duckling: End the session if they appear tired, cold or waterlogged.

As their feathers develop and become increasingly waterproof, swimming opportunities can gradually be extended.

Enrichment: Add a few mushed peas, greens or pieces of crumble to encourage natural dabbling, diving and foraging behaviours.

Transitioning to the Outdoors

Timing
Ducklings can begin transitioning outdoors as they become well feathered and better able to regulate their body temperature, typically around 6 to 8 weeks. Consider the weather, overnight temperatures and the individual birds rather than age alone. Provide additional warmth or bring them inside if conditions are cold or wet.
Shelter
Provide a secure, predator-proof shelter with dry bedding, good ventilation and protection from wind, rain and direct sun. Ducklings should always have somewhere warm and dry to retreat.
Outdoor Foraging
Introduce the outdoors gradually with short, supervised sessions, increasing the time as they adapt. Access to grass, vegetation, insects and shallow water encourages natural foraging, dabbling, preening and bathing behaviours. Always provide shade and fresh drinking water.

Socialisation and Behaviour

Humanising
Keep unnecessary handling to a minimum, particularly with ducklings intended for release. Young ducklings can quickly become accustomed to people, which may affect their natural wariness and behaviour. Necessary handling for feeding, cleaning and health checks is fine, but avoid treating wild ducklings as pets.
Enrichment
Provide opportunities for foraging, dabbling, preening, exploring and social interaction. Greens scattered through water, shallow water play, safe natural materials, mirrors and soft toys can all provide enrichment. Keep items simple, safe and easy to clean.
Companionship
Ducks are highly social and should not be raised alone where this can be avoided. Aim to raise ducklings with others of a similar age, size and developmental stage. If you have a single duckling, try to connect with other rehabilitators or fosterers to find suitable companions. Mirrors and soft toys can provide temporary comfort but do not replace another duckling.
Bullying
Watch for persistent chasing, pecking or pulling at wings and tails. Bullying can quickly result in feather damage, wounds and bleeding. Check that there is adequate space, food, water and enrichment, and separate persistent aggressors if necessary.
Preparing for release
As ducklings mature, gradually reduce unnecessary human contact and increase opportunities to behave naturally. The goal is for wild ducklings to become independent, socially competent and appropriately wary of people before release.

1 5

Preparing for Release

Release should be based on development and fitness, not age alone. For mallards, this is commonly around 8 to 10 weeks, although some individuals may take longer.

Before release, ducklings should be:

Fully feathered and waterproof
Capable of strong, sustained flight for species that normally fly
Self-feeding and maintaining a healthy weight
Physically fit with normal legs, feet and wings
Demonstrating appropriate natural and social behaviours
Comfortable living outdoors without supplementary heat
Appropriately wary of people

Keep human interaction to a minimum as release approaches. Release birds with their siblings or established group where possible, into suitable habitat with appropriate food, shelter and water, during settled weather.

Common Health Issues

Angel Wing

Angel wing is a developmental wing deformity seen in growing ducklings and other waterfowl, where the outer portion of the wing twists away from the body instead of sitting flat. It most commonly becomes noticeable during periods of rapid feather and wing growth.

The exact cause is not fully understood, but rapid growth, excessive energy intake, nutritional imbalance and genetics may all play a role. Diets containing excessive treats, bread, grains or inappropriate feeds can increase the risk.

Early signs include:

One or both wing tips beginning to stick outward
Developing flight feathers sitting at an unusual angle
The wing progressively twisting away from the body

If caught early:

Correct the diet: Feed an appropriate balanced grower diet and remove high-energy treats, bread and excessive grains.
Increase greens and forage: Provide appropriate leafy greens and opportunities for natural foraging alongside the balanced diet.
Support the wing: Early cases may benefit from carefully positioning and wrapping the affected wing against the body. Wrapping must not restrict breathing, circulation or normal movement and should be checked frequently.

Act early: Once the wing has finished developing and the bones have hardened, the deformity may become permanent. Early recognition gives the best opportunity for correction.

Botulism

Botulism is caused by toxins produced by Clostridium botulinum, which can develop in decaying organic matter and warm, stagnant environments. Ducklings may be exposed through contaminated water, food, vegetation, maggots or decomposing animal material.

Signs can include:

Progressive weakness or paralysis
Difficulty standing or walking
Drooping wings
Inability to hold the head and neck up, often called “limberneck”
Difficulty swallowing

Treatment: Botulism requires rapid supportive care. Remove the bird from the contaminated environment, keep them warm, clean and appropriately supported, and provide fluids where safe. Activated charcoal may be considered following recent exposure, but severely weak birds may be unable to swallow safely and can easily aspirate.

Prevention: Keep water fresh, remove spoiled food and decaying vegetation, dispose of carcasses promptly, and maintain clean, well-drained enclosures. Pay particular attention during warm weather, when conditions can favour toxin production.

Bumblefoot

Foot problems are common in growing ducks and can range from mild pad irritation and pressure sores to deeper infections such as bumblefoot. Bumblefoot can develop when damaged skin allows bacteria to enter the foot, causing inflammation, swelling and sometimes a characteristic scab or ulcer.

Common causes include:

Hard, rough or abrasive flooring
Wet or heavily soiled bedding
Sharp objects or small injuries
Excessive pressure on the footpads
Poor footing or inappropriate surfaces

Prevention: Provide soft, supportive, non-slip flooring and keep bedding clean and reasonably dry. Regularly check the underside of the feet, particularly in ducklings being raised indoors.

Early signs: Look for redness, thickened or callused skin, swelling, scabs, heat or limping. Mild irritation should be addressed early by improving the flooring and hygiene and keeping the feet clean and dry.

More advanced swelling, wounds, infection or persistent lameness may require veterinary treatment.

For more detailed information, see our Bumblefoot guide.

Infectious Diseases

Wild waterfowl can carry parasites, bacteria and viruses without appearing unwell. These can spread between birds through droppings, water, food, equipment and direct contact, as well as indirectly on hands, clothing, footwear and hair.

Good biosecurity is particularly important when raising young, rescued or unrelated ducklings together.

Good hygiene practices:

Wash hands before and after handling ducklings.
Keep new or unwell birds separate from the main group.
Care for healthy birds first and sick birds last.
Change clothing or use dedicated gloves, footwear or coveralls between groups.
Clean and disinfect brooders, feeders and waterers regularly.
Keep bedding clean and as dry as possible.
Prevent wild birds from accessing brooders, pens, food and water.
Avoid sharing equipment between groups unless it has been properly cleaned and disinfected.

New arrivals: Ideally, rescued or newly acquired ducklings should be housed separately and observed for signs of illness before mixing with an established group. Where possible, avoid combining ducklings from different locations or rescue events until you are confident they are healthy.

Strong biosecurity protects the ducklings in your care as well as domestic poultry and wild bird populations around you.

Injuries & Trauma

Ducklings can injure themselves through fighting, falls, fencing, entanglement or panic, particularly as they become more active.

Remove hazards and separate aggressive birds where necessary.
Check wounds for bleeding, swelling, contamination or deeper injury
Clean minor wounds promptly and keep the duckling in a clean, dry environment while healing.
Persistent bleeding, significant swelling, deep wounds, fractures or difficulty walking require veterinary attention.

Regularly checking enclosures for sharp edges, gaps and entanglement hazards can prevent many injuries.

Nutritional Deficiency

Ducklings grow extremely quickly and require a well-balanced diet to support healthy bone, muscle and feather development. Nutritional deficiencies, particularly niacin (vitamin B3) deficiency, can contribute to poor growth, leg weakness, difficulty walking and joint problems.

Prevention:

Feed a quality duckling or waterfowl starter wherever possible.
If using chick starter, pay particular attention to niacin intake, as ducklings require more than chicks.
Brewer’s or nutritional yeast can provide additional B vitamins, including niacin.
A bird-specific multivitamin may provide additional support where the base diet is inadequate.
Avoid excessive treats or supplementary foods that dilute the nutritional balance of the main diet.

Watch for: Poor growth, weakness, reluctance to walk, enlarged joints, bowed legs or difficulty standing should be investigated early.

Splayed Leg

Splayed legs occur when a duckling’s legs slip outward and they are unable to hold them in a normal position. Smooth or slippery flooring is a common contributor, particularly in very young ducklings.

Move the duckling onto firm, non-slip flooring immediately.
Mild cases may improve quickly once good traction is provided.
More significant cases may require a soft leg hobble to hold the legs in a natural position while they strengthen.
Check frequently for rubbing, swelling or restricted circulation.

Early intervention is important, as splayed legs become more difficult to correct as the duckling grows.

Watch for signs of illness such as lethargy, reduced appetite, laboured breathing, or limping, as these can indicate underlying health issues. If you notice abnormal droppings, persistent weakness, or sudden changes in behaviour, it's time to seek help. Having a vet familiar with waterfowl on hand is always a good idea in case of emergencies.
