it’s probably part of their sorting out their territorrial issues.  Are they chinning things, or pooping in his cage?  They could be making sure this interloper knows that this is THEIR house!

Well, last night in particular he was just hanging out. Both of them were in there at one point. No fuss. I can’t be certain that they’re not pooping in there.

(now it’s like we’re talking to ourselves… )

If there is no fighting and they seem to be getting along, they could just be expanding a comfort zone with each other and are establishing a hierarchy in a non fur-flying manner.  So, I think I would say social call.  If it does get territorial with the pooping, limit their access and you’ll really want to try to introduce them to each other in a neutral territory because the bunny that has been there longer has "established" territory and be less open to being social and friendly with an "intruder". Binky Bunny has a good intro to bonding here:

Well, all I can say is "Whew". Sometimes a bunny wandering into another’s cage (one they haven’t bonded with yet) can create madness and mayhem. Just watch carefully.  And if there is no easy way for you to get in the cage and break up a fight, then you may want to prevent them from going in, but take this as a sign that maybe having another go at bonding might be worth a try.

Well, we didn’t mention this, but the following applies here:

1). The two groups were introduced for the first time in our new apartment–it was neutral from the beginning.
2). We’ve tried even "more" neutral zones, like the bath tub, to introduce them; it was less than satisfactory.
3). Their cages are right next to each other, so they’ve been sniffing (and staring down) each other for months.
4). Now they have "pooping" wars–Mangi and Sassy used to be respectable, totally litter-trained; now their "out" area is one big litter box.
5). I’m sure by now, Mangi is the Alpha bunny (although he never chins anything; very strange) and all but Butters has fallen into his rabbit logic; maybe he’s trying a new tactic. Not sure.

So, basically either they will NEVER get along, and separate time out with no interaction is the answer. Or, they will start to get along by spending time in the same cage. Or, Mangi will befriend Butters and Sassy wont–which will be just like her (she’s the tiny, cute, NASTY one).

I’m just looking for people to place their bets on which will be true.

Rabbits are soooooo unpredictable. I never place bets on them. I just watch and learn, watch and learn, watch and learn. Good luck!!

Oh, I forgot to mention that one member – I think Fujoethebunny, had a similar experience.  Neutral territories and stress methods only made things worse during her bonding efforts, and using less neutral seemed to work.  This is not the norm, and I wouldn’t recommend this as advice to the masses, but  bunnies never cease to amaze me and there are always the few that break even the most basic "we think we know it all" rules.  Bottomline is for success is observation and knowing your bunnies.   With trial and error, you’ll find what works and what doesn’t.

Keep us updated!

Just be sure you can break up a fight wherever they may end up.

Ah I see, well it will be interesting to see how things work out.  Binky Bunny has given you some great tips, she’s a bonding expert!
