I have a chick that hatched 5 hours ago. It pipped at the wrong end, and struggled. There was a tiny bit of yolk sac left and the umbilical cord is still attached. It's thick, and I can see veins in it. I've read it will dry up on it's own? How long does this usually take? This chick is very weak, laying on it's side, but it is chirping a lot and kicking. It still hasn't opened it's eyes. Do chicks like this often survive?
