I don't have a lot of experience because this is my first year breeding. I have produced 29 eggs so far this year and have 3 females left to lay. Out of the 29 eggs 25 are good. I had 2 that were not fertile, one slug, and one boob egg that went bad. All the bad eggs came from a female on the top shelf. She also laid 2 good eggs. Two other females on the top shelf laid perfect clutches

I keep my snakes on the cooler side. My tubs hot spot ran 85-89 all winter with the other side being 70-75. I have my air set about 84 in the summer, so my tubs are a little warmer on the cool side in the summer. I removed all of my hides, so my females would be more likely to self regulate their body temperature.

I'm in full agreement with lower temps. I might lower mine a few more degrees this winter. I have around 20 females that are ready to breed this next season.

This may not work for everyone, but it is working for me so far!

Good Luck
