Hello! Wondering what is happening with my 10 mo old Buff Brahma....she is the only one losing her feathers. I have checked for mites or bugs and found nothing. We have 3 Brahma roos and 29 other hens/pullets. I know the roos are active and think it might be over inteterest but no more one else has the issue. She isn't shy or avoiding anyone else....she eats with everyone else and is laying well. None have molted. Any thoughts?
