The only problem with covering is water spots dripping on the eggs is possible and bad air flow. You need to open the container every so many days to allow for air exchange but then you may get temperature fluctuations.
I use the substrateless method now since you can do away with lids and still have high humitidy. Much less risk of colapse, boob eggs or mold spots growing.
This is substrateless. Some sort of grate needs to be cut to size to fit the bottom of the tub. It sits on top of drenched egg substrate. SO eggs are at a high humidity but not sitting in the wet substrate.
Because you dont want anything sloshing around if you need to move the tub inside the incubator. You do not want the egg to come in contact with water. Its best to still have a couple inches of perelite or hatchrite or whatever you use, under the grate. This way you can keep it more wet for higher humidity but you greatly lessen the chance of rotting eggs from sitting in wet substrate.
