slight dimpling at day 31..

Yes they are in a shoebox tote with a lid, no air holes and they are on hatch rite, no egg crate.

I'd suggest adding a layer of press & seal under the lid. Maybe also adding a small wad of wet paper towel in the corner of the tub away from the eggs to bump up humidity a bit. Adding too much water to the substrate (if the eggs are on it directly) can cause issues/molding, so if these steps don't help, I'd suggest putting them on egg crate before adding water to the substrate.

Keeping in mind, I've never bred any of my snakes, so this is solely based on my forum readings lol.
