One of my chicks that hatched has a bad leg. This is my first hatch and I'm not sure if it's splay leg or a joint problem. The leg on the right in the pic is bigger- maybe swollen? When it sits that same leg kicks out to the side. It can hardly walk- kind of hobbles. It sometimes ends up on its back and can't flip over. I help it or another chick bumps into it and it rolls back over. Not sure what to do. Please HELP!
