Try hand feeding her. This settled my Rex down a lot. She is probably cranky because she was bred. My NZW does get bitchy after being bred. They nip just a little if I handle them too much right after breeding and they stomp. And most rabbits don't like people being in their cages... It could be that she's not used to people being in her cage or even being handled on a regular basis! Then she gets stuck with some buck she doesn't know and bred and she's in a new cage and everything's strange... Well... It'd be enough to stress out any animal. I had a similar situation back in November/December 2012, and that doe was kinda berserk on me. Now she's fine as long as I move slow.
I'd give her some time, space, and lots of snacks from your own hands. If you can give her rubs down the face while she eats something it'll help her settle down. If you reach into the cage and she growls and bats, don't back away until she chills out. Just freeze and hold still. Otherwise she thinks scratching you will give her what she wants (you running away). Once she calms down and isn't lunging/growling anymore, take your hand out. You can try this with gloves or trim her nails if being scratched is a concern.
