So, this

on April 7th, resulted in

today!!!!!!
I counted 23 eggs, but I could be off... I didn't want to handle the clump too long and may have under or over counted. All good eggies.
My question:
1. I'm using vermiculite as an incubation medium. Do I cover the eggs 100%? They are clumped together firmly.
If I cover them 100%, how can the eggs on the bottom hatch and survive? The bottom eggs have a couple rows of eggs and medium on top. ( I'm used to lizard eggs where you leave some egg visible for the hatchling to climb out, or they can suffocate themselves ).
2. Any other pointers on incubating for a first time snake breeding? I'm only experienced with lizard ( bearded dragons, leopard gecko's ) eggs.
Thanks
