colubrid eggs are tough. You can move them any way you want. Most stick together andyway so it it not possible, But as far as their toughness goes. I could jugle my eggs and they will still hatch, no problems.
As far as taking the eggs out of the laybox as she is laying. I do. Because some of my Florida kings in the past have eaten their eggs if I leave them. So I alway remove them as they come out. Then I go back and remove some more until she is done. Of course i do this gently and don't move the female.
Another thing I do is cut my eggs after the first one pips. I have had a much larger success rate with snake not drowning in their eggs. Some might say that is nature and meant to be if a snake cannot emerge. But i have lost plenty when I don't, and they are to valuable to lose. So that is your personal choice.
