Hi there, So I've had six chickens and 2 ducks for over a year now, out of the chickens one of them started the moulting process in the spring she seems to grow back some feathers and then loses them again. It's mostly all been around her neck and chest area. It's been about 6 months now and there is still no progress and she is almost raw looking around her neck... I'm getting worried because its getting colder out and in a couple months will be freezing. If its a disease/illness it's not contagious, none of the other chickens have it. She is completely healthy other wise. Please let me know of any experiences similar or ideas as to what it might be. Thanks!!!
