She wasn't really doing well in the coop (lost weight and pretty timid) and I was letting her out of her cage at night to stretch her legs and explore the coop. I went out this morning to put her back in her cage and let the chickens out. She was dragging her back legs (they were off to the side of her). I think she broke her back jumping off of something or running around. There wasn't anything knocked over. I put her in the smallest cage I have and she was eating and drinking. I was honestly hoping she was just stunned, but I think I'm going to have to cull her. I've never had to cull one of the animals before. I know she was just a stray and she never really warmed up to me but I hate having to do this.
