Yesterday I noticed our rooster had something strange looking under his wings. At closer examination I realized he had missing feathers under both wings but primarily worse under one. Bless his heart, I have no idea how this happened so quickly without my being aware. Im wondering if this is stress or mites. I dusted him with DE and sprayed the skin with poultry care although there is no visible wounds. This morning I took a very warm wet cloth and cleaned the areas which he did not argue about and then sprayed with the poultry care again. He is separated from his girls until he dries. Any other idea? Oh and I did not see any signs of mites on him and the girls all look fine.
