You could wait until she gets a few more feeds into her, but you should be fine for a very short handling session. I would start out with about 5 minutes or so to start with. Do worry if they get a bit defensive, to them you're a huge giant of a thing that might eat them. Just try and stay quiet and steady. Don't let them think that their behavior will impact your reactions. (ie. If they hiss, pick em up anyway) Best of luck.
