I have a bantam hen that has a bald back at the moment, which I'm assuming is from the younger of my 2 roosters. I never see them pulling her feathers out, though, which is the part that confuses me. Anyway, some days her back is a tannish color, and recently her back has looked red like it's sunburned. Is this sunburn? And is it going to hurt her if nothing is done about her? She's on the skiddish side and won't really let me touch her. And is there a way to help get her feathers to grow back without isolating her?
