This is a courtesy post for a relative who also just got chickens. She just noticed her 4 week old Rhode Island Red chick has a leg that looks like this (pictures below)... She says her chick isn't acting like it's in pain unless she touches the leg. He is still eating, drinking, and acting completely normal. Any idea what happened? It looks like it could snap in half. It is going into a holiday weekend, and so it would probably be difficult to find a vet. Any suggestions?
