Hatchrite

I put enough water that it lightly clumps when you squeeze it. Put the eggs in there...you can bury them if you want, I leave the tops visible to check their condition. If they are in a big clump though, I bury all but the top. I place a slightly damp moss on the top of them and close the lid. I rarely have to add water because with the lid closed and sealed, the moisture stays in. I add if the tub starts seeming a little light in weight or the perlite seems super dry. You can just add a bit of warm water to the sides and the perlite will take the moisture without soaking the eggs. As long as the eggs aren't directly in the water, you can't drown them in perlite. Vermiculite though clings to the eggs when it gets too wet and will drown them. I've never had a problem with the perlite ever. As long as your egg tub seals well, you shouldn't have to do more than check them every so often.

aww, well thank you that helps alot!
