What Naturstee said about feeding her treats through the cage bars is great advice, that is one thing I would do also. My main advice for right now though, is only to handle/disturb her if absolutly necesary. What I do when I get a rescue that has fear agresion, is for about a week or so, longer if needed, I only come close to them for feeding or health care. When I feed, I talk to the rabbit quietly and calmly, even if they try to scratch or bite me. What this girl needs right now is security, so that she can begin to learn that not all humans are cruel. And it may take a long time, I have one doe that I have been working with for almost three years, and she still gets frightened very easily.
I know there are others on here with more experience than I have, this is just whatI have found works for me. My two cents, LOL.And while I would hate to do it, it probably would be the best to get her spayed immediatly, it would jsut add to her problems, and yours, if she were to have a litter now.
