It's been too long since I hatched shipped eggs. I can't remember the best position for lockdown. Sitting up in an egg carton or laying down? I received an almost completely scrambled batch of eggs. 3 of the 18 developed. Lockdown in 2 days if they keep going. The air cells are really bad. Not saddle shaped but really messed up and bubbly. Would it be best to leave them upright? Or try laying them down?
