What to Feed Ducklings | Complete Feeding Guide

Getting duckling nutrition right in those first critical weeks determines whether they grow strong legs and healthy feathers. The wrong feed or missing a key supplement can cause permanent problems before you even notice. Here’s exactly what to feed your ducklings at each stage, what to avoid, and how to handle the most common mistakes.

Starter Feed: The First Two Weeks

Ducklings need a starter feed with 20%–22% protein for their first two weeks of explosive growth. The ideal choice is a non-medicated waterfowl starter crumble if you can find it. If not, use a non-medicated chick starter and supplement with niacin—ducklings require roughly three times more niacin than chicks for proper leg and bone development.

The niacin supplement method that works: mix brewer’s yeast into the feed at roughly 1.5 tablespoons per cup of feed or ½ cup per 10 pounds. Feed should be available free-choice during these early weeks, and always paired with clean, shallow water. Ducklings need water to swallow properly and cannot eat dry feed safely.

Medication warning: Never feed ducklings medicated chick starter. The medications in standard chick feeds are not formulated for waterfowl and can be harmful. Always check the label for “non-medicated” or “unmedicated.”

Transitioning to Grower Feed

After the first two weeks, ducklings should move to a lower-protein grower feed at 16%–18% protein. Exact timing varies by source and breed—some recommend switching at 2 weeks, others at 3 weeks. Call Ducks may need starter feed for up to 4 weeks simply because their smaller mouths struggle with larger pellets.

If you cannot find a waterfowl-specific grower, a non-medicated chicken grower with continued niacin supplementation works well. Ducklings can eat starter/grower feed all the way until they reach laying age at approximately 18 weeks, at which point you transition to a 16% layer feed. Our tested duckling feed recommendations cover specific brands that meet these protein requirements.

Safe Treats and Common Mistakes

Treats should stay under 10% of daily intake. Good options include dandelion greens, chopped grass and weeds, peas, leafy greens, mealworms, scrambled eggs, and moistened oatmeal. Hard-boiled mashed eggs work as an emergency ration if starter feed runs out. An emergency mash of rolled oats and cornmeal blended to a crumble texture will keep them fed temporarily, but it is not a complete diet.

Never give ducklings bread, chocolate, onions, avocado, citrus, salty or sugary foods, or dry beans. If the starter feed’s protein content seems too high for your breed, uncooked oats mixed into the feed can dilute it—but oats alone do not make a balanced diet and should only be a temporary adjustment.

Stage-by-Stage Feeding Summary

FAQs

Can ducklings eat regular chicken feed?

Ducklings can eat non-medicated chicken starter or grower feed, but only if you supplement niacin through brewer’s yeast. Chicken feed alone does not contain enough niacin for healthy duckling development.

How often should I feed ducklings?

For the first two weeks, keep starter feed available free-choice at all times. Ducklings grow rapidly and need constant access to food. After that, three to five feedings per day works well if you prefer scheduled meals.

What happens if ducklings eat medicated feed?

Medicated chick feed can cause health problems in ducklings because the medications are formulated for chickens, not waterfowl. If accidental feeding happens, stop immediately and switch to non-medicated feed. Monitor for unusual behavior or appetite changes.
