I have some 6 day old chicks that were dropped off today and 1 has a backwards leg. They are from our preschool teacher. She said the chicken was eating and acting fine, so she couldn't bring herself to cull it. I've done some research in the few short hours we've had it and a few things I saw suggested it could be a tendon issue, but I didn't want to do anything that could harm it, if it wasn't. I've included a picture below. Any advice would be welcome. THANK YOU!
