Question - how do they get started cutting through the egg shells?
If memory is correct, snake eggs are softer than bird eggs, yes?
They are attractive little critters.
The hatchlings have an "egg tooth" attached to their snouts that they use to get out of the egg. I was able to observe it for the first time with these guys. The "tooth" is actually a hardened upper lip that has a sharp edge across the bottom. If you run your finger across it just right it almost feels like a knife edge. The snake uses it to cut a slit in the eggshell so it can get out. Within a few days of hatch, the egg tooth softens and is no longer sharp. It then comes completely off with their first shed.
The egg tooth would have been difficult to actually see if I hadn't known exactly what I was looking for.
And yes the egg shells are not rigid like bird eggs. They are flexible and have a texture more like thick paper or something. They are kept "inflated" by the fluid pressure of the amniotic sac, which is why they dent in and collapse when they get too dry.
