Hey,
You really have to bear in mind that these animals were probably accustomed to a regimen of some sort, and if taken out of their element and introduced into a new one, they must be made to feel comfortable and safe. If you can get them to adjust to their new digs then that's half the battle. Food shouldn't be a problem once they are used to their new home. Offer them food only at night when the lights are just out for the first time in the course of the early evening and when they are most apt to be prowling for food. Offer them food from a pair of 12 Inch forceps that is either freshly killed or warmed up if the food was frozen and thawed.
If that fails on the first attempt, try again a half hour later. Sooner or later you will get a feed response either defensive or other, but they will react and eventualy take the food from the forcep. I've fed many babies like this and have gotten them all to eat using this technique. Food can also, be left just in front of the entrance to the hide box or placed half way into the hide head first. If you use this technique the food should be warmed up and waved in front of the hide box opening gently pausing occasionally to wait for reaction and strike. They are ambush predators and are not active hunters so if what lurks in front of their nose is food, and of the right kind, they will eventually take.
