A year ago I received a shipment of eggs that had some broken and most of the intact eggs had the air cells messed up. I did not have information on how to deal with them at that time and layed them on their sides and hand turned them as I did all the eggs. Some developed and three hatched, but out of two doz. not a good hatch at all.
Then I read to stand them on the small end and let them rest an extra long time, put them into the bator standing on the small end and not turn them for a few days and then start turning them. That gives the air cell a chance to stablize.
I have a shipment of pretty little blue banty eggs that arrived with most of the cells floating and I am following that advice. They have been in the incubator for 1 day now, standing on the small end. I hope it works.... I really want a good hatch from them. If the way I have them proped up continues to work, I will leave them and just tilt them several times a day.
With standard size eggs, it is easy - just put them in an egg carton if you don't have a turner - and put them in the bator in the egg carton.
