How old is the chick? If it is spraddle legged you can fix it with a band-aid, but it needs to be done in the first few days before the bones (I think it is?) harden. It is very simple, and even if it isn't spraddled, it won't hurt the chick. Just take a large bandaid and cut it in half lengthwise. Use the gauze part as a spacer between the feet. Wrap one ond of the sticky around one ankle, and the other sticky around the other ankle, and fix them to the gauze. I was told to leave it on till it fell off on it's own, but mine was on for a week, and didn't fall off. I can't even tell now which chick it was!
Did this one have any trouble hatching? Mine bled a lot when it hatched (thanks to my DF deciding to 'help' it), so that's why I think it was like that. I haven't had any others hatch like that.
