I went out this morning to let out my birds. I have 11 chickens 4 geese and 4 turkeys and I found one of my Cochin hens huddled in a corner with all of her feathers on her back gone and her back covered in blood. I have her isolated in a small pen with food and water. It was the best I could do in 5 mins I have to go to work very soon, so I'll keep it short. What should I do? Please help.
