My Arucana(Henny Penny) is having her feather shafts be damaged and pulled out on the rump by one of my Wyandottes(Jenny). Its getting bloody and the other chickens other than Jenny are starting to peck at it. I'm afraid it will get worse and start to get infected. Would separating Henny Penny from the other chickens help? If so, any ideas on a quick shelter to house her in?
