Somehow 2 of my hens got in my back yard with my dog. He attacked them. One has cuts on her back that I have treated and have her inside. Other is in worse shape. First I thought a broken leg, but there are no marks or breaks I can feel. She dies have a deep puncture on her back I have treated but her right leg looks limp. She is alert but not active or wanting to eat. How many days do I wait to see if she will heal? I dont want her to starve to death. I had a roo that was attacked by a coyote last year that was pretty beat up and after a week he made a complete turn around. Any help would be appreciated.
