My Dark Brahma hen ( 10 months old) has been broody. I have been trying to break her from it. I have noticed when I pick her up she is missing her stomach feathers. My brother has parakeets and said somtimes birds will pluck out their feathers because new ones are growing in and are itchy? For now I'll separate her from the other birds..She doesn't have any mites....Any suggestions? I don't know what going on with her feathers!! :/ Forgot to mention - When I went outside to check on the girls, she was in the hen house. When I picked her up out of the hen house she had dry yolk where her chest, where the feathers are missing. Where she was sitting there was no yolk, whites, egg shell.....Totally confused!!! I looked around the hen house and every where they were last night and this morning and I can't find anything!!! Any ideas of what that could be? Thanks!
