I am aware that blood rings=no chick, but when I candled this morning I saw that one egg had a blood ring with a dark blob toward the fat side of the egg, as if an embryo was there. Could it just be a blood spot? I don't know, but now I'm afraid to remove it-I don't want to kill anything growing. Also, can the bacteria from one bad egg travel to another? I hope not. I just noticed another egg with what looks like 3/4 of a blood ring. Does that count? Or is it something else?
