My 2 week old chick has a large bump on her hock that looks like its coming thru the skin. At first (when she was a few days old) I tho't she had spraddle leg and hobbled her. She didn't get any better and I gave her polyvisol in her water. I isolated her in the brooder with her own water and food and yesterday noticed that her neck has been pecked on thru the fence that surrounds her. When I picked her up yesterday I noticed the huge bump on the top of her leg, and she still won't use it. I don't know what is wrong or what to do next! I lost one of my babies at the beginning to spraddle (I guess) and was devistated, I love my babies and really don't want to go thru that again. Thanks for any help you can give me. Jeanie
