Here's my post on this from a couple months ago: http://ball-pythons.net/forums/showt...Hatchling-Help
We had problem eaters and had a lot of solutions from members here. What did it for us after four weeks or so of refusing their first meal was live mouse hoppers. We wanted to get them started on F/T rat pinkies but the anxiety of them not eating after four weeks eventually pushed us to just give them live hoppers.
