I have a 5 week old baby chicken who was doing well but today I noticed it stumbles once in a while. When it gets up to walk, the baby chick will stumble backwards or sideways some times. It baby's the right leg. My daughter noticed that while it was eating today it was laying down and it's right leg was crossed over it's left leg!! It does get up to walk around at times and see what the other chicks are doing. It does eat and drink and the two other chicks aren't pecking at it. Could this baby chick have a minor leg injury or something more?
