As far as the egg carton method, I am not as enamoured of it as many are. One thing you need to know in incubating the Blue Orp eggs you just received from me is that, since they've been molting heavily, I have had issues with wrong-end pippers. However, since I've put them on Game Bird Breeder feed, there have been fewer and fewer of those. I dont remember if Missouri Chick and Livinzoo had any pip the small end or not. You may have no issues like that at all whatsoever (they've been on the supercharged feed for two months now), but the carton method is going to be iffy with that happening, if it does, as you know from past experience.
