Then I'm even MORE sketched out Trev. If they are willing to give up a female that could give them $10,000 worth of eggs for like $100, then something must be up. So the fact that they are "proven" (and how can they PROVE that?) doesn't make me feel any better because the only people I would even consider buying an adult animal from would never be selling adult female BP's in the first place.
Plus, with proper planning, a Ball breeder can work it so that he's never in need of adult female ball Pythons. I honestly couldn't use one right now unless I bought another co-dom. But when I do, I have another 12 females growing up.
