I just got my chicks from MyPetChicken on Tuesday morning. They all looked fine, and then yesterday I noticed my Cochin is limping badly. She won't put any weight on her right foot. She stretches it all the way back, when she wakes, and can raise it to scratch her head. But she hops along on her left foot to walk. I don't see anything on it. She's eating and drinking fine. Any suggestions? On another note, my polish chick is missing a toe nail!
