Honestly, in my opinion the human can be better at it than the snake. You should also factor in what your plans are. If you want to attempt breeding again next season, you need to get her off the eggs so she starts eating again. If you are like me and believe there is the possibility of gold in every egg you won't want to bet on how good a mother she is.
On the other hand, if this is a learning experience for you and you want to see how they do it naturally go for it if you think you can keep the environment right. I would be ready to pull her off the eggs if things start to go south. Sometimes there are rollouts that are good and you may have to incubate anyway to save the egg. I am not against maternal incubation and will probably give it a try myself one day preferably on a clutch that I am not counting on.
