I feel your pain and am sorry this happened to you. I was recently dusting one one of my favorite black star hens in my lap when she all of a sudden jumped off my lap. I instinctively caught her by her right leg and put her back on my lap. When I put her down on the ground she hobbled off on her left leg, holding her right leg up. This happened a month ago and she still hobbles on one leg. I keep her in a cage in the garage and she gets special treatment. I'm still feeling guilty, angry and sad about what I did. I'm afraid I've permanently crippled her, however she'll be living the good life til she dies. She has layed me an egg every day since the incident. I'm not giving up chickening, I love them too much.
