Wow, it is early in the year for wood turtle eggs. Congrats.

Were they hibernated?

I have noticed that wood turtle eggs are a bit more senstitive to high incubation temperatures than many other turtles. I incubate at a range of between 80 and 83 degrees F. Since sex is genetic, and not temperature dependent, you can err on the cooler side. They hatch quickly...I have had anywhere from 45 to 60 days...usually 50 or so.

Good luck. If they are viable, they will chalk a day or two after laying.
