So I read that for shipped eggs it is best to hatch them I an egg carton, tilting rather than turning three times a day, so the air bubble is sure to stay at the big end which is of course up. So...I see how this works for incubation, but it said to leave them in for hatch. How can a chick hatch out of a vertical egg in an egg carton? (the lid is cut off). But wouldn't that make hatching harder? Has anyone ever tried this, and is it really a good thing to do for shipped eggs?
