Well, this is a good place to hang around & keep reading up. I've bred some other kinds of snakes (not BPs) but you never want to rush this anyway. You'll get far better results with snakes that are fully mature, not rushed into reproduction when they're barely old enough...even if it is feasible. I never bred snakes younger than 4 years, fyi. You also don't want to breed a snake that you haven't had for a while (best would be a year, IMO) because re-homing is stressful, & it also takes TIME for subtle issues to become obvious & to be treated. You want any snake you breed to have the best health prior to putting that strain on their body.
You also want to make sure that any snakes you produce will have good homes- if you care about them, you don't want to "flood the market"- there are already so many ppl breeding BPs, & consider that in an "iffy" economy, people don't have money to spend on pets. I don't want to sound like a "wet blanket" but please think about all this, & don't let your enthusiasm drive your ambitions. If it's a few more cool snakes (or a "neat project") you want, it's honestly cheaper to just buy them- when you breed snakes, there can be expenses you might not anticipate (such as vet care) & some challenging issues, such as what if you produce a bunch of snakes that are viable but not salable? (ie. hatch with defects) Please think about all this, much as we welcome your fresh enthusiasm.
