I have a couple of 1 year old Rock hens. One of them I noiced has a right leg that "gives" out when she stops to feed or turn. It does not happen all the time but enough to make me worry. She will collapse on her right side/bottom and then hop back up and and go again. It seems to be more prevelent when she is standing still and turning or changing directions. But she does fall over. I am assuming she has twisted it or the hip is/was dislocated. Not sure if I can do anything. She doesn't favor the leg and seems to not be in pain. Any ideas would be appreciated!
