I so hope you can move her indoors! If you have her spayed she’ll be easier to potty-train. I have 2 bunnies indoors and I didn’t think my yellow one could ever be trusted to roam free, but he’s calmed down considerably after his neuter. I’ve covered all cables and keep several litter-boxes around the apartment. Since my bunnies hate each other I’ve put up a gate covered in netting between the living-room and the hallway. It’s been working very well, much better than I dared hope.
You don’t have to let your bunny roam free indoors 24/7, you can start with a supervised hour a day or so. It took my yellow bun about 3 months to become a good 24/7 free roamer. Last week he made an illicit and unexpected expedition out on to the balcony and ate some pelargonium-flowers, though, so make sure all bunny-inappropriate pot-plants are out of your bun’s hungry little reach.
Rabbits tend to get mites when they are under stress. They most often have some mites always but they don’t start to multiply unless the bunny get under stress. Both my bunnies had mites when I found them. It’s easily treated and not really dangerous. You can help your bunny by combing out the dandruffy flakes once the treatment has kicked in and killed off the mites.
