Hello.. so i need some advice…
We (me and my boyfriend) recently got a second rabbit to bond with our current one, Nibbles. Nibbles is our baby and we wanted her to have company when were not home during the day. So we got Moxie about a month and a half ago now… and things haven’t been too good. At first they were doing great, and then one day that got in a fight. Idk if it was a bad one of not, because I have never seen a bunny fight or show any aggression. But it seemed awful to me. Both were okay though, just fur mess(they both have lionhead so theres always a LOT of fur) We let them cool down and started the dating process over. But they were (and still are) housed in adjacent areas. They can’t get at each other but can still see each other, which they loved before the fight… The dates weren’t very good, they would fight or just stomp around each other. And then Nibbles started acting out. She started stomping and digging on us and just acting out. Which she has NEVER done. We tried moving moxie out of the room (we have a bedroom set up as a bunny room) but we only live in a two bedroom apartment, so there isn’t really somewhere she could go permanently..I would be fine keeping her in the area next to nibbles and just keeping them separate, but they both seem MISERABLE. The vet said moxie is 4, so an ‘older’ bun. I don’t want her to be getting stressed out and it effecting her. Or nibbles.
Ive no idea what to do. Does anyone have any advice or experience on this? I know all the basics to bonding like taking it slow and being patient etc because Ive done a ton of research on it. But Nibbles isn’t herself anymore and its making me sad. 
Also last night Nibbles woke me up and had gotten out of her area (happens every so often because she loves to escape. Its a game for her and once she gets out she just comes and finds me. surprisingly alway at night… I just find what she jumped off or squeezed through and fixit) And so I put her back and noticed fur in moxies area. Like fur from a fight. I freaked and checked them both and they were both completely fine… but still. AHH! Idk if its good or not that she went in and fought and LEFT, like so stopped fighting? idk.
