I feel your pain. My male Pied, who was pounding a small f/t rat every other week, has decided to only eat 1 live mouse and not every week, he seems to skip some weeks. The normal I have also refuses f/t and gets fed a live mouse every Sunday, and now my HRA Super Pastel Lesser is insisting on live mice. At least the normal and the HRA never refuse and if the pied decides he's not going to eat one weekend I have a whole rack full of other BP's that will take a live mouse in a heartbeat.
Hang in there you have a sweet assortment of BP's to start dumping them.
