My pen was broken into by my neighbor's dog. She got ahold of only one of my hens thank goodness. My hen seems ok except for her right leg. It is limp. I can not feel a break anywhere but when I hold her up her leg just hangs there. It feels the same as the other leg which she is using and while down...holding straight behind her to hold herself up. I have only had my chickens since the first of December and I do not know what to do. She is in a box in my bathroom for now. Any help would be appreciated.
