I can tell you from our past experience taking in some fiesty females that what you've been told is true. Just go about your business with this snake, wear gloves if she gets serious about the biting stuff, be gentle, calm but firm and confident in your handling of her. If you need to restrain her to move her safely, do so quickly, hesitating on a behind the head grab will get you nailed (I've been there and it only took one lesson to learn that LOL), don't allow her to set the tone for your interactions.

While it's appropriate to respect the snakes we own and not push them past what is reasonable, for some of these bigger ones that are unused to handling or have been handled roughly, you need to rebuild a handling pattern with them. Make sure that removal and return are done as you were advised - with calm and assured movements. Don't allow her back to her enclosure until she is calm, even for 2 seconds.

Some will never accept much handling but most will do fine once you set a simple routine down with them. BP's really respond well to the same things happening over and over. Once they get that this routine causes them no harm, most will accept it other than the occasional "back talk". Some won't though. We have one female here that recently has started throwing her weight around so we're being cautious with her (she draws blood) and working to show her that we aren't intent on hurting her.
