Dr Seward, I don't know if you've answered the question in this forum already or not. If you have, sorry I asked it again. What ever happened to you trying to sex Heloderma through a DNA blood test? I heard your source for the testing in the lab dried up. I assume you are still trying to sexing them through the ultrasound process. I like your nest box you've created. Know that you've simplified breeding to a science, maybe you'll be able to discover an easier, quicker, and accurate way to sex Heloderma.
