The chick does have a laceration on his leg and I have cleaned the cut with peroxide. But he's not using his leg at all. Not even his toes. I've seperated him from the other chicks so they won't pick on him, but I'm not sure what I can do about his leg. Any advice would be greatly appreciated. I hatched these chicks to replace the bird that got mauled by the neighbors dog so its survival is extremely important to me. The chicks are only 4 days old .
