I hate the never cut/ let nature take its course crowd! Are there 120 volt outlets in the wild for mama ball pyhtons to plug their incubators into, no. The only people in my opinion that can say that is people who maternally incubate.
Bottom line, you bred them. Without you the eggs would not exist. I have learned that my magic number is day 58. After I cut, they pip that night or the next morning.
Don't let people try to make you feel bad for cutting.
And yes, I cut mine because by the end of incubation I am impatient! I want to see what I helped create.
