You have to make sure not to roll the eggs, or the air pockets will move and the embryo will suffocate. Keep the humidity around 85 to 100, and heat 74 to 80. Make sure it does not exceed 80, for the babies will hatch malformed. Place a humidity and temperature gauge and lay some dirt or wood chips with snake bedding in the incubater (use a chicken incubater). Don't directly spray the eggs, and immediately remove spolied eggs. If you need more egg info, tell me.
