So I've been looking on the net and I couldn't find anything about this topic. I was wondering if anyone knows around what month a ball python embryo starts to develop their reproductive organs. A friend of mine who's been an owner of an exotic pet store for around 30 years now, says that it's not perfect but he tends to get a higher number of females if he does low to moderate temperatures during incubation and a higher amount of males if he does higher temperatures. Now I know some of you out there are going to say that temperatures do not affect ball pythons sex outcome but it still would be fun to try for myself. Thanks to all for your time and your feedback!
