Hello, I have 1yr old Reds and only one is experiencing feather loss on her breast and not laying. Skin is bright red and appears smoothe no visible breaks or bumps on the skin. Hen still eats and takes mealworm treats, in a year I've never seen any excessive "pecking order abuse" so I don't think it's bullying. I looked closet at her visible skin and feathers didn't notice any mites or other pets...any help is great! Can I put anything on the skin itself to reduce irration or soothe her?
