My banty rooster is 2-3 years old. He's had this bright red skin, almost as bright as his comb for over a year. It's on his belly (?), sorry don't know chicken terms. Anyway, I've seen other places like around the edge of his wing. He's very healthy and gets DE dips regulary. I even gave him a flea shampoo at one point. I don't think he has mites. Does anyone know what causes this? I have a video of him floating in the (dog) pool and you can see it.
