She most likely was force feeding them due to the stress of the conditions you described. RTBs are know for a killer feeding responce all 3 of mine are killers. Leave it alone for a week keeping the temps and humidity right and I would guess he will come around and start eating. Force feeding should be a last resort since it can be very tramatic on the animal, since he has feed several times you have some time to work with him. Unless he is really small he should be able to take a fuzzy/sm adult mouse with no trouble.
