Heck Ryan if that male BP is eating mice well I wouldn't mess with what works at all. Just do as Becky suggested and if he needs more, offer him a 2nd course mouse once the other is well down into his body cavity (usually within minutes of swallowing the tail down). If he wants to eat more he'll take it, if not you can just pop the mouse into a small kritter keeper and fatten it up more for next week's meal.
