Hello, So I have one Rhode Island Red, only 3 days old and he's been doing this weird thing with his leg. I couldn't get a picture, so I drew it. He's hyperextending the hock joint at the knee, which makes his ankle overextend as well. I could not find reference to this anywhere. I have given him a splint for splayed legs (it was the closest thing I could find), it seemed to help to begin with, but now he's turning his entire body in order to hyperextend the knee and rest on it. This chick is the only one that constantly shudders when I pick him up (is that a pain signal?) the leg has full normal range of motion plus some abnormal flexability. No swelling or redness. However, he is constantly "Alarm" chirping. What can I do? Should I put him down? If I do have to put him down, what's a good, humane way to do it? I don't want to end up with a chick killing itself or being in pain, I'll put him down if I need to.
