A. You don't say whether this is a new rabbit for you or if your rabbit was once house trained and now is acting out these bad behaviors. If she was once a good rabbit and her behavior has changed suddenly, you may want to have her examined by your veterinarian to rule out a medical problem.
It's true that spaying can help with aggressive behaviors such as biting. And the older a rabbit gets, the less they will chew. But it sounds like your rabbit may not be properly house trained. It's normal for rabbits to want to chew, and if left unsupervised they don't know they're not supposed to chew on couches and electrical cords. If you want to have a house rabbit you will have to either encase the cords in heavy-duty plastic or block them with furniture. Providing appropriate things to chew on and places to burrow, such as a cardboard box filled with hay, will help redirect her. Many people confine their house rabbit to a cage or small area when they are not able to supervise. Or consider confining her to a rabbit-proofed area with a baby gate.
When you are holding her, try to make it for short periods of time at first, because rabbits often respond to overstimulation by biting. You can reward good behavior (not biting) with treats such as raisins and apple slices. If she does bite, put her back in her cage and try again later.
Until your rabbit is spayed, she will definitely NOT do well with another rabbit. I would recommend that you wait to let her adjust to her current situation before adding another bunny to the mix. Rabbits generally like having a companion, but she will probably spend less time interacting with her human companions.
