I have three Buff Orpington pullets that are 7 months old. I noticed about a week ago that 2 of them have combs that are laying down. It's straight up on the beak side of the head, but about half way towards the back of the head, it's laying down. I'm not sure if there is any reason for concern, but it just doesn't seem right. Anyone expirience a similiar situation? Is it a disease/sickness? Could it be a vitamin/mineral deficiency? Is it just something that happens for no reason, and there is nothing to worry about? Thanks for your input.
