To be quite frank, you're most likely going to have better success at artificial incubation, especially if you've got no previous experience hatching eggs. Maternal incubation is quite difficult. My advice would be do this the other way around. Master incubation first, attempt the harder maternal incubation when you understand what the eggs need a little better. I too tried maternal incubation the first time, and I failed miserably. I had four eggs and no hatchlings. If you truly want to do this as a learning experience, you'll learn much more if they actually hatch.
It's quite possible that your female has already ovulated, but 99% of the time, females ovulate in the spring. Again, that's not always, as Bree here had a very late in the year clutch herself, but typically you should look for ovulations in the spring. If your female ovulated, and you were looking for it, you can't miss it. Not to be harsh, but if you wanted to breed your snakes for the learning experience, you really should have tried to learn something about breeding before you attempted to do so. There are several websites that have a breeding page (myself included) where you can get all of the information on what to look for . . . or look for a "reputable" breeders page. Don't always go by youtube videos; some know what they're talking about and some don't. I myself researched on The Snake Keeper's website before I attempted, and there was still a learning curve between reading what to do and actually doing it correctly.
