Generally, due to the stress of being moved from one home to another, it's not a good idea to try switching feeding routines at the same time. Yes, bps can be finicky eaters, but most can be successfully converted to F/T with enough time and effort. I (and most others here) would advise you to let your snake settle into his new home, then feed the same kind of prey the breeder was feeding. After your snake is settled in and feeding regularly, THEN make the switch to F/T. You'll likely have a lot more success that way...
