So. She has a bare back, lost 5 Henson, and she is taking over with the roosters I guess. I have put a saddle on her to prevent more problems on back, but today we noticed he vent is featherless, and moves in and out with her breathing. Shes a bit "mucky" back there, as though she has poo problems as well she acts normal. I have taken her out of the flock for now. Any ideas?I did feel around and there was not anything that felt like an egg in the immediate vent area.
