Hi all, I'm new to raising chickens and concerned about one of our hens. She's losing ALOT of feathers, especially around her rear and near her wings with a little on the top of her head. She's just barely over a year old. There are only four and they are rotated between little paddocks. They have more then enough room, have a balanced diet and I haven't noticed any pecking..ever. Our Great Pyrenees also keeps predators to pretty much zero. I've considered that she may be molting but she has lots of feathers broken off mid-shaft. Is that normal? There was a bunch of feathers in her dust bath today. Any advice? Thanks!
