I dont want to rain on any parades here, but how long have you been keeping snakes? Are these your first two?
I'm only asking because we see TONS of people on here looking for breeding advice LONG before they're ready.
If youre a first time breeder you'll likely have a hard time moving the animals, so be prepared to keep most if not all for a while.
Not to mention, the BP world is already ridiculously over saturated. For example, there are over 16,250 BPs available for sale right now on morphmarket alone.
Just food for thought. I'm not trying to discourage you.
