well rabbits just like any person or animal need to be well socialized from the time they are very young. the fact that this poor bunny hasn't been well socialized plays a big part in it's behavior. your friend shouldn't just stick her hand in the cage and try to pick the bunny up. rabbits are naturally fidgety animals, this will only make it even more scared. your friend so slowly try to get the bunny adjusted to her and her lifestlye. the cage should be in a place where it is fairly quite, but not a room that nobody ever goes in, if possible put the cage up on something so that rabbit is closer to eyelevel, so that the rabbit can see if someone enters the room, and so it doesnt feel threatened by any other animals. she should spend tiem trying to get to know it a little better maybe by sitting near the cage and soflty talking to it, letting it smell your hand first and giving it soem treats. my rabbit always liked carrots, banana, and apple. after a while the rabbit should hoppfully get used to her and she should spend much time with the bunny as possible : )
