#1) I would wait at least one week before feeding her. I sometimes feed earlier if I know the last time the breeder or person I got the BP from fed the animal. I also like to try to get it on the same schedule as the rest of my collection as soon as I can.

#2) I'd give the snake at least a day or two after the first feeding before trying to handle it (so you are looking at 8-9 days after you get the bp). I'd also keep this in mind after future feedings. You don't want to handle too soon after the snake eats as you could risk regurgitation of the meal.

#3) I personally feed mine in their tubs. I have 30+ snakes and do not have time to take each one out into a separate tub. I also have no issues with aggressive snakes from feeding this way (with the exception of hatchlings who can be nippy until they put on size).

Other than that enjoy your new bp
