I am in the same situation. My 10 year old picked up my fascination with reptiles and got me into the breeding end of it again. I bred colubrids mostly back in the 80's when captive breeding first started taking off right around the time of the first National Breeders Expo back when they were in Orlando. I also was and still am amazed with Ball Pythons and the genetic diversity and have no regrets about building my collection. I have two seasons of hatching about a dozen clutches behind me now and still feel like a kid on Christmas morning when I see a nose sticking out of an egg. I would say the hardest part of this is selling the babies. I didn't really have any intention of making a profit but I didn't expect I would have to wholesale really nice well started snakes for pennies on the dollar either. I admit that I haven't put a whole lot of effort into marketing and perhaps I could have done better in that regard but, that's my advise. If you are looking to sell these babies with any sort of return on investment, buy carefully, and work on a plan to sell them well in advance. Some sort of marketing plan to separate you from everyone else out there selling similar animals. Good luck and even if you end up wholesaling dirt cheap it is still an awesome experience you can share with your son.
