I picked up 3 baby chicks from my local store on Saturday. I had them on reserve and was told by the clerk that one of them had started having problems with one of her legs that day. First, I was surprised how small she was. I think she is a bantam and was mixed in by mistake with full size. She is 13 days old now and still smaller than my Rhode Island Reds that are 5 days old. The problem is she will not use her left foot. She keeps it in the air and hops from place to place. Sometimes it is shaking, but I think that is primarily because she is trying to keep her balance. She does not seem to be in pain. I did notice that the hock joint on that leg seems bigger than the one on the other leg. Any suggestions on what I can do to help her?
