Lmao never seen a post like this before. I bet for every 30 posts on a bp being a picky eater there is one on one being an overly aggresive feeder. Maybe next time you feed try a slighty larger prey animal. Go for a f/t small rat. Then he will probably go back to his lathargic working up a poop ways.
I would be ecstatic if I were you lol. And feeding outside of the cage is not a must... It's only really for handlers who Dont want a feeding response when they open up there cage to take them out. IMO I love a feeding response when I open up my bps enclosures. A lot quicker to feed :-).
Be happy! You have an established eater :-).
