You can leave the snakes in the incubator as long as it is big enough, to have enough air trapped inside once the lid is closed. I wait until all the snakes from a clutch hatch before moving them, although, this year I might put them in their own hatchling rack tub as soon as they come completly out of the egg. My incubator tubs are styrofoam and about 10" x 16" give or take. So, there is plenty of air in their for them, plus, there are tiny imperfections in the top of the styrofoam where the lid rests, so I am sure a bit of air circulates that way. This is a pic of one of my incubator tubs, just prior to me placing the babies in their own tub in the hatchling rack.
NOTE: I do not use the plastic grid at the bottom, that was a one time experiment
