Or it could take 5 or 6 years before the female lays a clutch, the first clutch could be all slugs, or you could have 2 or 3 eggs (all males).

People thinking putting one snake with another = $$$ in the bank need to think again those are animals and things can happen, if it was that easy and always working out the way people want to, a lot more people would make a profit, instead a lot of people think they can and then 2 or 3 years later when they don't because not everything always go as planned they will sell off their entire collection (tons of ads like those online)
Again it is possible but the majority of people are in the red for a few years before even breaking even let alone make a profit.
