This morning I found one four month old chick dead another one weak and listless...both are Brahmans, I also took a four month old silkie into the house yesterday for the same reason. They are drinking, but not too interested in eating and weak. I have seen what appears to be a bit of bloody poop from one one of them. Should I force feed? The two who are ill are in the house together in a dog kennel, where I can keep them warm and watch them. My adult birds are fine and the other seven assorted four month old chicks seem well. they have been in the main coop for about a month, beside the older birds, but not mixed in yet. Any ideas what I should do?
