Sorry for the double post not used to mobile app yet. Geeky I would leave them fat side up for 3 days then start tilting in carton and not candle again until day 5 or so. They get so jumbled from shipping. You're right about the propping of carton I did this second clutch, nothing hatched, I also didn't let them rest beyond 24 hours. You're right about wanting to treat them as non shipped eggs if the cells are not detached though. I agree with Bama about the keeping them in cartons the entire time till hatch not being good. Good luck, I looked at images of those SFH they're beautiful birds!
