So I know the little ones shouldnt eat the layer feed until they start laying. Im wondering if they could eat an organic feed as long as it didnt have any oyster shell or calcium in it. Its kind of a pain having to lock everyone out of the main coop when I let everyone out, I dont want the little ones going in there and eating the layer feed for the older girls, so I was thinking about switching everyone over to a nice organic feed for the time being until they get to their laying age. Is is just calcium in a layer feed that is harmful to the chicks?
