I have about three laying hens that have horrible bare spots on their backs. I know that, for the first one at least, it was a spot created by one of our roosters being overly friendly. Well, those roosters are long gone and now I have at least two other hens who have developed the same bald spot problems. Our hens have molted so that is not it, unless it take some hens almost a year to molt! But this is not molting kind of feather loss. This is bright red bald spots that look really ugly. Is it other chickens hen pecking them? I've never seen one doing that so I don't know. Is there anything that I can put on it? I'm just thinking that if some feathers don't grow back soon we're going to have some serious frost bite issues come winter. Any thoughts?
