If they had been laid last night you are probablly fine (no guarantee). I have moved eggs a couple days after laying and they still hatched. Hope this helps
First and second year females for me usually have a 50% or less hatch rate.
After that it is 100%
There is a chance that you might have put it exactly how it was, I did the
exact same thing once and the egg hatched, I was lucky that I got it back
in the same position it was before I flipped it.
