Splayed leg? Ankle hyperextends?

Unbind it and give PT and see how it is fairing, then bind it back up and repeat tomorrow. Eventually, it will get better.

As of today there seems to be some progress. The chick was able to bend it's ankle a few times normally and take a few semi normal steps without falling. I noticed quite a bit of swelling around the knee though, so I trimmed some of the feathers and looked at it closer. His knee is bruised, swollen, and bends backwards. It can straighten out easily, but it will only bend the wrong way. I feel bad for not noticing, but I though for sure his problem was with his ankle, since it hyperextends. I'm not sure if his knee is dislocated, broken, or just didn't form correctly. The chick can still get around and is quite fast. Is there anything I can do?
