What Do Ducklings Eat? | Complete Duckling Feeding Guide

New ducklings eat mostly commercial starter feed, but their needs shift fast as they grow. Getting the right protein level, knowing when to switch feeds, and offering safe treats without common mistakes will keep your ducklings healthy through those first critical weeks. Here’s exactly what ducklings need at each stage.

What Starter Feed Do Ducklings Need?

Ducklings need a high-protein starter feed designed for waterfowl, ideally with 22–22.5% protein for the first two weeks. Waterfowl starter is preferred because it has the right protein and niacin levels. If you cannot find waterfowl starter, an unmedicated chick starter at 18–20% protein is the common substitute, but only for the first four weeks. Never use medicated chick feed — the medication can harm ducklings. When using chick starter, supplement with niacin or brewer’s yeast to prevent leg problems and growth issues.

Ducklings eat free-choice (food available around the clock), and they need shallow water at all times — deep enough to dip their bills and clear their nostrils, but shallow enough to prevent drowning.

Feeding Ducklings by Age: A Simple Timeline

Ducklings eat different feeds at different ages, and the transition between feeds matters. Here’s the straightforward schedule from day-old to first egg:

For Call Ducklings (smaller breeds), wait until 4 weeks before switching to grower pellets because the pellet size may be too large. Transition feeds gradually over about a week — mix the new feed with the old, increasing the ratio daily.

Safe Treats, Greens, and Supplemental Foods

Ducklings can eat a variety of treats in moderation once they are eating starter feed well. Starting around 3–4 weeks, offer small amounts of chopped greens and grass clippings. Safe treat options include dandelion greens, chopped weeds, grasses, peas, moistened oatmeal, small vegetable pieces, fruit bits, mealworms, and other insects. Introduce new foods one at a time, and always keep them in small pieces to prevent choking.

Standard poultry grit can be introduced at around 16 weeks, but only once ducklings start eating anything beyond commercial feed — the grit helps them digest fibrous foods.

What NOT to Feed Ducklings

Some foods are outright dangerous for ducklings, and others are nutritionally worthless. Avoid bread entirely — it fills them up without nutrients and can cause health problems. Also avoid junk food, salty or sugary items, chocolate, onions, avocado, citrus fruits, raw or undercooked beans, and fruit pits or seeds (apple seeds, cherry pits, etc., which contain toxins). Never feed medicated chick starter, and never offer hard, choking-prone foods too early or in pieces that are too large.

Common Duckling Feeding Mistakes

The most common errors keep coming up with new keepers: feeding medicated chick feed (the medication can be toxic to ducklings), skipping niacin when using chick starter (leads to leg deformities), using deep water bowls that can cause drowning, and offering bread or nutritionally poor scraps as a main food rather than a rare treat. Stick to the starter-and-grower schedule, keep fresh water shallow, and your ducklings will thrive.
