I offer my 750g female a small rat weekly at her size, won't handle her that day, wait till she's moving around at night(usually around 9pm) then won't handle her the day after feeding. I'll move a rat from the freezer to a container with hot tapwater (1 drop dechlor) to thaw for 20 min and warm up. Then sit on top under a heat light for 5-10 minutes to warm it up above 90 and get her excited by the scent, then zombie dance with tongs, wait till she wraps it, then jerk it a couple times so she coils it tighter. If she doesn't take it after a minute or two of dancing it around infront of her, I'll put it back up top and wait 5 min to try again. If she still doesn't take it I'll leave it overnight and clean it out if still there in the morning and wait till next week. This was the only way I could get my previous picky BP to feed when I first got into it about 15 years ago, my current enchi bee has been much easier to feed, but I'll stick to the technique.
