I would leave her alone for a week, and let her adjust to being in a new home, before handling her and feeding her.
It would probably be a good idea to get a fecal done on her, sinice she was fed WC mice, she could have picked something up from one of them.
In my experience, Kings are generally a bit more skittish than Corns are.
In time, she may just become accustomed to handling.
Don't forget to add some pics of her!
