Corn Snake Egg Incubation?

Being kept at 95 degrees for too long will kill them. Veins are a sign that the eggs were or are fertile and the veins will still be there even if the eggs have gone bad. However, usually they will turn moldy if they are bad. With that said, I have had eggs take up to 70 days to hatch, but warmer temperatures will sometimes cause them to hatch quicker. I personally incubate corn snake eggs at a steady 81 degrees.
