Congrats on the lock, but as far as not quarantining, I don't care how pristine a breeder may be, things can happen, what if she had started to develope an RI just prior to you getting her, you put her with your snake, now yours has it to, even worse, said breeder is exposed to IBD and unkowingly exposes said female prior to shipping, now your male has it also, like I stated QT is a must.
I don't care if Christ himself showed up with a snake especially made for me, you can bet your buns, it will be in QT for 3 months.
