Help! One of my month old silkie chicks suddenly is walking with its feet curled inwards, as far as they will go. I suspect something is wrong with one of its legs because it wont put a lot of weight on it and the hock joint is bigger than the other. I cant figure out why both feet are involved??? Other than that, it zooms around with the others. They are on med. chick starter. so I wasnt thinking it was nutritional. Any ideas?
