Last night something tried to get into my coop. I heard the ruckus and went out to chase it off. One bird was hurt on her leg. This morning I can see that her leg has been badly injured. I have put her by herself. Her leg is so badly damaged that she cannot use it at all and the skin on the 'thigh' has been taken off so that you can see all the meat. I have put food and water in her cage but she has not touched any of it. What can i do to help her? I she lives it will be without the use of her right leg. Any suggestions?
