Erik,
This isn't something you want to mess up.
You need to get quarantine between boas and balls exactly right if there is a possible IDB issues with the boas.
I'm not talking just on a snake health issue here I'm speaking on your chances of ever selling a single ball python to anyone ever.
Lay out your quarantine rules, especially between species, or the previous posts are going to bite you in the butt - a lot.
