One chick hatched last night with a birth defect on its foot. It cant bend it or move it and the toes dont spread out they all kind of stick together. The other leg is fine but he cant really walk and the other chicks sometimes step on him. The foot has a big red spot on it where the leg attaches to the body. He did hatch a little late. He hatched late on day 23. What should i do? Is my only option to kill him? I would really hate to do this but it is cruel to make him stay in the brooder with the other chicks and him getting stepped on. If i do need to kill him what is the best / most painless way for me to do it?
