Just curious how is your tub setup? They will not eat for various reasons from too hot, too cold, too big of a hide (security). Don't know how you feel about braining f/t mice but i'd had success with that as well. I use a small plant saucer to make snug hide, and place a brained F/T fuzzy in the hide. Usually overnight they eat but if that fails in my opinion a little stress for the hatchling is much better than watching it deteriorate. If you do assist feed be prepared to have it spit it out and having to repeat the process (push the pinky on the upper lip to open the mouth, insert feeder, close mouth, pull prey a little back to catch on teeth and place BP back down). Good luck, none eating hatchling is the most frustrating part of breeding.
