I'm gonna have to cull the little guy. The splint helped the hyperextending, but he twisted his leg so it sits naturally pointing directly to the right, away from him. Then I took the splint off and his leg is worse than ever. He's gonna have to go, poor guy. I did everything I could think of to help him, it just didn't work out I guess.
Thanks for the help though!
Sorry to hear this. But it makes no sense to keep a defective member in the flock. You tried, I guess it's just not meant to be. Nature probably would have taken it out anyway.
