Hello there!
I agree w/ the rest that you should do what works for you and your snake.
BUT! I think you should take into account the act of conditioning your snake.
I think FatBoy does this by a consistent schedule.
Others do it by scent introduction.
Others, like myself, like using a feeding container.
I think I read somewhere that BPs in the wild are kinda conditioned by rainfall. Which makes sense to the point that during rain, rodents will emerge from their burrows?
I am a believer that BP's and many other animals must have an environment that doesn't preclude them to perform certain actions. This is why a lot of posts infer: that the less stress you introduce, the better.
BUT! I think that if their cage environment is the best for them (the living environment is perfect), moving them to a container time after time on a consistent basis, is not stressful.
The feeding container can be used as a "feeding signal",,,,,,, just like time, scent, or rain.
When I put my BPs into their feeding container, within seconds they are poised to snatch the forthcoming prey. I also like the feeding chamber, because it doesn't matter whether I feed them on fri., sat., or sun.,,,,,doesn't seem to matter at what time.
Also, If I left a dethaw on top of the cage? HA HA, my cats would totally have a party with it!
I do what works for me.
