However, when the female Mallard duck lay eggs, her diet changes to include more animal life than plant matter. In general, Mallards typically eat more plants than animals, and they also eat more plants in the fall and winter seasons. Food selection also has to do with the shape and style of the Mallard's bill.
Many of these foods are similar to the natural seeds, grains and plants the birds will forage on their own. As omnivorous birds, ducks will eat a great deal of different foods, and the best foods to offer ducks include: 1  Cracked corn. 2  Wheat, barley or similar grains. 3  Oats (uncooked; rolled or quick).4  Rice (cooked or uncooked). 5  Milo. 6  Birdseed (any type or mix). 7  Grapes (cut in half). 8  Frozen peas or corn (defrosted, no need to cook).f you do choose to feed ducks and waterfowl at local ponds occasionally, the best tactic is to visit rarely so the birds are not getting excess food that would be unhealthy for them or their environment.
