Change the hides to something more solid and enclosed. Perhaps bump the warm end up to 31-32, but ensure that doesn't overheat the cool end. Then try feeding at night, try not to be seen or heard and offer the fuzzies on the end of long forceps/tweezers. If they're still not interested, you will need to get them to strike at the fuzzy, so you'll need to annoy them with it a bit, but not too much or they'll stress right out. Rubbing the fuzzy along their neck usually initiates a strike. After a couple of strikes they should hold onto it, then gently back away so as not to disturb them and they should consume it.
