Totally depends on the snake, but rules of thumb generally exist in this hobby for a reason. You can't harm her by leaving her alone for a few weeks, but on the other hand, you probably won't tweak her mentally if you throw a rat pup in there tomorrow. If, however, she shows no interest in food tomorrow, then I would certainly let her settle for about 10 days or so.

Most baby BP's start to calm down with proper handling. But, then again, the most beautiful BP I ever owned was evil from the day it hatched. I called it the little ball of hate. That snake is in the hands of a local breeder now, and weighs in at about 2100 grams, and she calls him the Incubus...seems he never grew out of it. So, totally depends on the snake
