I hatched five chicks a couple days ago and one of them has what I think is "splayed leg syndrome" but I'm not sure what to do about it. She (and I only say "she" out of hope) seems to have one normally functioning leg and one that is constantly extended and she cannot bend the "knee" or ankle joint to walk. When I bend it carefully for her, she doesn't seem to be in pain. However, she is in pain getting trampled now 
Any suggestions on what to do about Gimpy?
