I have 1male 1 female khacki campbell ducks that are around 4 months old. My ducks are living with my 11 chickens and getting along great. The chickens even taught the ducks to go into the coop at night. The boy duck is actually king of the coop right now and I had some very bossy girls in there that he put in their place. They are all sharing food right now. Can the ducks eat the same food as the chickens? The chickens are on 16 % layer pellets with some oyster shell mixed in. I had the ducks and 2 baby chickens on Purina flock raiser. Are chicken layer pellets ok for ducks?
