I have a mixed flock of 10 hens and 1 roo. One hen, Ms. Rosie, a year old EE was hiding behind the nest boxes for a week, I thought she was going broody and just left her alone. After about a week I checked on her and she had most of her saddle feathers missing with hard yellow skin exposed. We are certain our aggressive mating roo had been going after her. She had lost so much weight and could barely stand or open her eyes. I brought her into the house, my kids and I got her to eat and drink and she perked up. I kept her in the house for about a week but she was trying to escape the bin so I brought her back to the coop after roosting time. As soon as I brought her in Big John hopped down to go at her agamlm nin. She went back behind the nesting box, where I am guessing he can't reach her and he went back to bed. I separated him from the flock for a few days but noticed she was still hiding. So this afternoon I picked her up to check her healing. She was pecking at it but I thought maybe it was itchy as it healed. It looks awful. She doesn't smell sweet or rotten and is eating/foraging and drinking fine. She followed me to the house tonight so again we have a house chicken. Has anyone seen anything like this before? Any tips on how to help her heal or even if she will? Thanks!
