I found a cute little (fill in animal name here) and I'm trying to raise it as a pet. Can you offer me advice?
A waterfowl diet consits mainly of vegetation and seeds. However, most duck species eat some animal matter part of the year (insects, worms, snails, freshwater shrimp). Mallards, from which most domestic breeds were developed, have animal matter make up about 10-15% of the diet, and then only at certain times of year (ducklings in particular eat a lot of insects as it is an important protein source). Diving ducks have a higher amount of animal matter in their diets, as high as 95% in the king eider, a sea duck found in the Arctic. Coots also eat a fair amount of animal matter, which is how they get their nickname of "mudhens" (from rooting around in the mud for animal matter). Ducks and geese are perfectly capable of finding enough food for themselves, however, if you feel you "must" feed them -- remember it is illegal in many municipalities -- feed them whole grain like oats, or dry cat or dog food.
