New snakes should be quarantined for at least three months, to make sure they have no disease or mites. Also, BP's after a few months of age should not be permanently caged together. This can cause unnecessary stress. They can breed, especially now while the females follicles are still enlarging, but this can endanger your female if she is under 1200g.
I would give them separate cages until ready to breed.
Hope this helped![]()
