Who's way?I had very poor hatches doing it your way.
I gave a lot of thought about what was happening to the yolk and air sac being in constant shift during shipping.
From that perspective, I thought maybe I can reform it's shape but it required the heat of the the incubator to help liquefy the content while the egg is set in the right position with the help of the egg carton. Hence why I gave it 3 day to reform and settle into the right position. And it actually worked.
