What kind of snakes?
Many people who regularly breed colubrids recommend cutting any eggs that haven't pipped within a couple of days after the first pips.
I did that with some from both my corn snake clutch, and my gray-banded king snake clutch. They came out within a day or so and have done just fine.
This is my favorite baby picture I have taken so far this year. A hypomelanistic striped corn snake. A real tough guy!
