It has a large lump on it's neck and a lot of yolk was coming out of the egg before it totally hatched, and the yolk looks green. SHould I be worried? will this contaminate the rest of the chicks if it's bad? SHould I get the chick out and the egg out before the rest get sick? I would post pics, but my original comp internet is not working. it doesn't even look like it's totally formed, and all the yolk is coming back out!
