Yes the female knows how to incubate better then us. If they ate in africa in their world under natural circumstances but not in captivity where they live in tubs with a human syressing them out, disturbing them, cleaning their cage, opening and closing their tub to look. Yes they know how to regulate temps, but why chance it. You can be succesful with maternal incubation but when incubating eggs you want the odds in your favor. Your best odds are when you incubate with an incubator. It does not take long for eggs to go bad if they have too much temp flucuation. With a good incubator you dont have this problem. I have a walk in incubator made out of a converted walk in closet and i can control every aspect of incubation perfect. I have excellent odds with large quantities of clutches. Whether your doing 1 clutch or 100 clutches your main goal is not to loose eggs so if you can sway the odds in your favor then why wouldnt you do it. Again im not saying you cant do maternal incubation but im talking odds. Now i know a couple big breeders that do maternal incubation but if you saw their setups and the scope of the money that they spend on their facilities you would flip. So whats it worth to you? Too many people think cause they see the ball python market that they can get into it and just put snakes together and make a fortune are kidding themselves. You have to spend money to make it and at the end of the day it is a money driven industry and you wouldnt have the morphs you have today if it wasnt.
