Taking her out into another feeding tub is just stressing her out and possibly making her even more defensive. I wouldn't even dare reach into my snake's tank when I'm thawing a rat in my room. She gets all predator mode and tracks everything with a heat sig which include my hands! (she eats like a pig).
And you really have to leave her alone for at least a week. It's way too stressful for her. I would even say 2 weeks!
