My 3 month old chicken hops on one leg. The joint (what I would consider the elbow) is twice the size as the right leg. I can move the leg and she doesn't complain but I can feel a popping. This is the same chicken that could not walk when I took her at 10 days. I was told it was a calcium defeciency and she eventually did walk. A little unsteady but she walked. A couple of weeks ago I noticed that she was limping again and now she holds the left leg up and hops on one foot. Closer examination shows the joint twice the size. So I am not positive it is broken bunt not sure what else it could be. I have wrapped the joint with medical tape for now. She doesn't like it. Anyone have any ideas?
