Yeah, if the air cells are really bad, it's better to handle the eggs as little as possible for a few days. Good luck with your hatch! My eggs should be arriving here in a few hours, and they'll get a quick candle, then sit for 12 hours. THEN my next Serama hatch will begin *cooking*
If you can gently candle your eggs when they arrive, you can see what the air cells look like. Then yes, let them settle for at least 12 hours, large end up, at room temperature before you put them in the incubator. I don't turn my shipped eggs for about 3 days, but if the air cells are really bad, you might want to leave them a few days more. They CAN hatch, so don't be upset if they look displaced when they arrive. Incubating and hatching shipped eggs mostly upright is the best bet.
