Weak leg 2 day old chick

[akaruby]

So I've done a lot of research on this site and I'm still stumped as to what is going on with my little chick. Her left leg seems weak and she falls over on to that side and can't right herself.

It doesn't seem to be slipped tendon, I felt the joint and didn't feel anything out of place. It doesn't look swollen. I've vet wrapped her legs with a hobble to help keep her leg underneath her better. Now I just have the left leg wrapped. She can walk well that way but still stumbles and falls over on her weak leg. It hasn't been a full 24 hours that she's had her leg wrapped.

I've also given her some poly vi sol.

Any ideas on what could be going on?

Just wanted to add she is moving around pretty good, still falling over from time to time. When should I remove the vet wrap? Is it possible it's a sprained leg?
