my neighbors leopard geckos laid two eggs today in their egg box. When he brought the box over, the eggs rolled... so we have no idea what side of the egg was originally facing up. I candled them and they both have veins... on one egg the veins are on the top of the egg... the other egg the veins are on the bottom. How do I know which way is up? should I move them now, or just leave them alone and tell him to be more careful next time?
