mine is a bit different too... i have some now that will take anything. at first i do the live when raising my babbies, then to switch them over i dont go directly to frozen, but i pre kill them and offer right away. next feeding i pre kill some rats but let them sit for about 10 minutes or so so they cool off for a bit. then i do this a few more feedings and the very last i offer frozen thawed. sometimes i also will thaw a frozen and thaw feed the live feeder first, and if that snake dont take it off the bat i feed it to the ones i know will take frozen. just keep trying
