Switching from live to FT/PK?

I want to switch my BP from live to FT. My other 2 snakes are eating FT (my corn) and PK (burm). I've tried a few times with my BP but it doesn't seem to like the FT. I'm tryinh again today. The bp struck and knocked it out of the tongs, but no coil or much interest after that. I'm going to leave the mouse in there for a little while today while I'm out and about. BTW It didn't feed last weekend due to a shed, heck I knew not to even try with her. I had a mouse in the freezer, which my wife found the hard way (she thought it was a melted popsicle or something till she picked it up :8: ) Anyway I thawed it and giving it a try.

Is there any tricks to get it to take the FT more readily?

I had to do that with my bp also. Just try it and if your bp won't take it, make sure the rat is REALLY warm. Mine won't take it unless its fresh out of HOT water. Other than that, I don;t know what to tell you. I'm pretty new to balls.
