Wow.. You really have tried it all. I read an article from Justin Kolbylka a while back and he was advocating moving the snakes around in the racks that were problem feeders. I had one snake that was strictly on mice and I moved him around in the rack random times over a few weeks. Sure as hell that snake took a rat like 3 weeks later and has been on them ever since.. I was kinda surprised. But hey.. It worked. Sounds like you have done this already though by switching her around in different tubs, substrate etc.. I'm not trying to throw salt at an open wound here but I have NEVER had a snake refuse a live mouse.. That has always been my fall back.. hahahaha
