From this point I'd say in a few days, up to maybe a week, she'll shed. You can certainly try to feed while she's in shed...some will eat while in shed, some won't. If you feed live, it's no problem. Just pull the mouse/rat if she doesn't eat. F/T...you can try but if she refuses you'll have to re-freeze, which is generally okay to do once, but may result in a messier feeding next time.
