and they are not Turkins. I have 2 Black Australorp hens who's feathers are disappearing from there necks. From the looks of them it seems the feathers are pulled out. Red and irritated. They are in with one Silkie roo in wait for their mates that are just 5 weeks old. Laying everyday. I have bad back problems and can't chase them or get close enough for some photos. Anyone have an idea what might cause this? I have some food grade DE I am going to through into the coop this morning. I don't know what else to do. rj
