I'm incubating 3 silkie eggs, and two eggs started the process before the other one. I think the third is infertile. But anyways, my (oldest I guess I would say? Lol) egg was growing very fast and looked healthy. They are both fertile, but I candled it this Morning, and the yolk is very big, and there's a large shadow at the fat bottom part of the egg, and it wasn't there yesterday. Theres still big red veins on the side, but I was just wondering if this is normal? I hope it's still alive. Any advice? Will be well appreciated!
