Thank you guys for your replies!
Glad to know at least one of her morphs - Pinstripe. Maybe in the future I'll see if anyone nearby has a normal male I can breed with her just to see how the babies come out and learn what she is once and for all (minus any possible hets she might have though).
I think since she seems to already not be a picky eater, like nikkubus said, as long as I am patient I think I will be able to eventually get her onto frozen/thawed. I was able to switch most of my current BPs from live mice when they were young (a few months old) so I do have experience with it. I was just a bit concerned with what Bogertophis described - the rare possibility she will not want to accept f/t over live since she is older and only known live her entire life.
But I'm more confident after nikkubus stating that given enough time/patience, it should be doable. I always make the head warmer than the body of the f/t rats when I feed them to my current snakes, although I do it with hot water (and a ziploc bag) instead of a hairdryer.
I'm really surprised that it's possible for her to be just pinstripe, like snagrio said regarding the bright dorsal (and the solid line right down her spine), I thought that meant she had to have something else in there! Some of these morphs vary quite a bit, it's so interesting.
Thanks again!
