Don't take this as THE WORD on the subject because I'm just repeating what I've heard here, but usually they don't hatch. There was a thread a while back about someone trying to hatch a double yolk egg and people were telling her that. I think she did get one chick out of it but the other didn't make it or something like that.Has anyone hatched a double or a triple yoke? Do they live? Are they smaller as adults?
