I'm raising my first batch of chicks and have one bird who is struggling. It's 3 days old and has curled toes and a leg injury/deformity. I've addressed the toes with boots that I made of bandaid and cardboard but the leg appears to be the bigger issue. It has red spots (like scabs) on the joint and is cannot be straightened. The chick is eating and drinking and trying to hop around but is already being picked on by the other chicks. I thought about splinting the leg but it won't straighten fully. An ideas on what could be wrong?
