Arteficial Incubaton = higher clutch rate
Maternal Incubation = Variable results but generally lower harch rate as you loose a few eggs
Species of snake won't matter it's about providing a stable incubation period for the eggs. Maternal or nesting may result in more drastic temperature fluctuations not to mention mold could take hold from the environment vs a sterile (meant to be) artificial incubation medium in an incubator with stable hemps and humidity.
You can make pretty stable homemade incubators out of an old bar fridge or wine fridge and a heatcord controlled by a pulse thermostat... I've even seen people just do it out of styrofoam boxes and get pretty stable temps out of them.
Here's a home made one I use.... the temps varry only 0.5 degrees no matter what the external ambient temps are (even in a heatwave or a cold snap)
Cheers
