We have 3 almost 6 month old pekins (2 gals 1 guy) the girls have just started laying. we also have 3 younger ducks (8wks old) 2 pekins and a black blue swedish. We are beging introductions and need to know what to feed the group once they are all together. Currently the older ducks get flockraiser (we also have 25 chickens) and the younger ducks get starter grower feed. Any advise would be greatly appreciated.
