Some funny posts on this thread for sure,feeding in or out of the enclosure is probably one of the most beat to death topics Ive seen, but honestly im sure the rat/mice bones hold a lot more density than aspen shavings so theres no reason to feed outside their enclosure ESPECIALLY newly acquired bp's as most are stressed enough from the change in environment. Typically a stressed bp will refuse to eat or defensively strike at the prey, I would recommend to stop offering food for a few days to a week and then offer food inside the enclosure. Every bp is different, they have different personalities, some stress very easy and some not.
