The chick is about 2 weeks old now, and other than the leg is perfectly healthy. About 3-4 days after they all hatched, I noticed this one's leg was funny. I figured it was spraddle leg, and treated it so. But now I know it's not spraddle, sometimes it's leg'll twist almost 180* to the side. The chick doesn't seem to be in pain, but I'm worried. Can I do anything to help... or should I put it down?
