For what it's worth, when I've incubated & hatched snake eggs- (many times successfully, & never lizard eggs, btw), the eggs were in moist vermiculite, covered with but not touched by plastic that had one or 2 pin-holes in it, & the only time I ever opened the plastic over the container was to remove a bad egg, to adjust the humidity, or to briefly candle (check on) them. Best of luck!![]()
