I have an australorp hen that has hurt her leg or foot. She will try to walk on it but it is more of a limp. Her toes just flop. They turn under her foot when she does walk. She doesn't walk much. I'm guessing that it hurts to bad. She is a free range chicken. We brought her in the house last night cause she couldn't climb up in the tree to roast. Her foot is swollen. She gets mad if you touch it. Any idea what it might be??
