Hi - I have 11 chickens in my coop. All hens. No roosters. Tonight I came home from work and one was dead on the coop floor. They've been pecking each other alot this winter (first winter in the coop). Is it possible that they pecked this one to death. Yesterday, she was acting perfectly normal and laid an egg. Neck feathers were all stripped. Most of the other chickens are missing feathers too.
