I have a hen that lays one of those every day. All with double yoke, but I did get one with 3 yokes. I was told that this would calm down and happens when the hen is excited and that it normally happens when they first lay. Or at least until they get use to laying. But she has been laying since August like this. She will wear herself out. Can't put in an egg carton because there is nothing big enough. I just use them for baking.
