The best foods to feed ducks includes cracked corn, wheat, uncooked oats, rice, defrosted peas and corn, earthworms and chopped lettuce. The food must be in bite-sized portions easy for ducks to eat, and one must follow local regulations on feeding ducks.
Ducks can be fed food that has similar nutritional profiles to the seeds, plants and grains that they eat naturally. Ducks must never be given bread because it provides them scant nutritional value, and this can inhibit the ducks' development. Chips, popcorn and crackers are also bad for ducks. Any food with mold on it can kill ducks.
