No i was thinking more like the snakes absorb whatever oxygen is in the egg and the yolks therefore causing moisture to expelled out of the eggs? Bc i believe ive heard of condensation forming on the eggs once they start to dimple. That would also make sense bc if youre noticing higher humidity once the eggs start to dimple then that would mean they are expelling excess moisture through their shells. Well thats my theory at least, tho i really am not sure lol.
I could be wrong, thats only what ive gathered from observations.
