corn snake eggs can sit in a deli cup up high on a shelf and still hatch. ...put the ball eggs in the incubator and put the corns on a shelf or on top of the refrigerator. they will hatch. no magic needed. good deal doing a trade and getting eggs as well!!! score. hopefully for some cool mojo babies to pop out soon. dont worry about rolling the eggs. dont you think in the wild when a female is incubating them her self that the eggs will be moved everytime she does...it doesnt matter. they will hatch if they are good.
