Yesterday I noticed that Cleopatra, one of my Australorp pullets, who is seven months old and the queen bee of my little flock, is missing feathers on both sides of her neck. She otherwise is healthy and active, laying large eggs regularly. None of my other chickens are missing feathers. I don’t see signs of mites. I looked at Cleopatra’s vent and it looks normal. My chickens have plenty of space in their run, a large, well ventilated coop, and get to forage in my yard nearly every day.
Does anyone know what is causing this?
