I noticed my hen is missing many feathers. I have checked for lice and mites many times on several occasions and have yet to spot one bug on her. I spray my coop with a permethrin based solution whenever I clean it. I do not have any roosters. Is she just that low on the pecking order that the other hens are doing this to her? The redness reminds me of what lice can cause. What is wrong with her?
