I don't have a count of how many meals she had with the breeder. I got her from Garrick at Royal Constrictor Designs and he made it sound like he doesn't ship snakes until they are good eaters. I know she was only 45-50 grams when she hatched, so in two months she has gained some good weight. He said he was going to feed her last Wednesday or Thursday.
I've been pretty lucky when it comes to switching from live to f/t and from mice to rats. Not one of my BPs so far has so much as blinked when I changed it up on them so I'm prepared for her to give me some trouble. My luck has to run out eventually.
I'm going to try f/t next week because I have them on hand and if she takes it great, if she doesn't I'll drive across town for live next time.
