I did end up setting up an incubator. The eggs are in there at 85 degrees F.
If it had been summer like with the colubrids I would have tossed them on the shelf like I do the corn/king/milk etc eggs. That has been a fool proof method for me for years. However it is way too cool to do that now. I had expected her to lay months ago. It is going to turn out okay regardless. Who knows if any of the others will end up laying any time soon.
