Well, I've been following your thread and feel I'm not quite that far yet... Mine are doing fine on the patio set-up. So well they were getting on that I dared put them together indoors. I dissolved Deirdra's condo and changed the room quite a bit. I blocked off the access to underneath my bed  to allow the trio access to only  open space. Deirdra and Mops are so close now, even Deirdra will groom Mops (it used to be only the other way around.. ).  It's so cute, too, since he has the long face furnishings it looked like she was flossing her front teeth with his cheek hairs...
I put them all into the room. Things went well, there were treats waiting for them, the dogs were lounging and I observed... I stayed up so late drawing out the sssion but then Lint started chasing Deirdra and she screamed as he grabbed her fur. Now she is more afraid of him than before. He seems to have gained his courage back to go and try for a humping... and she will not have it.

Here they are at the beginning of the session...

I'm glad I took this photo because now it seems unreal that it really happened. Lint lied down first and D came after. Check out his expression, though, what is he thinking?

Lint is actually unhappy with this threesome... he is only keeping from chasing her off because Mops is between them.

After Deirdra screamed because Lint scared her, I put them in new territory in my yard in an L-shaped run.

...where they sat sat like this for the duration of the session after Lint had nipped at Deirdra right away when I put them in.

you can see Deirdra here very tense after she tried exploring the narrow run and getting nipped for it.

--I'm now setting up a pen in my basement to have a neutral place indoors where they will interact (nothing new happening in the bathtub). I believe very much in the paired bonding for trios/quartetts etc. where you introduce each bun individuallly to the new bun, but in my case here, Mops definitely seems to keep Lint from chasing Deirdra.

Dexter screamed the first time he met Delilah too, after she got him. That scream is awful. Flossing her teeth with cheek hairs! hahaha  At least Mops seems to be keeping Lint in check when they're together.

Today went well, my new basement bunny zone is almost ready and will help, especially myself since watching the bonding sessions has kept me from getting other things done that I normally do in the basement.

On the patio this afternoon the normally uneventful time turned into a type of stress bonding delivered by the elments as we finally got the rain we needed !!

Rabbit bonding can be.... unexpected!

Yesterday, I needed a new strategy. I had been seeing no more changes on the patio, only the usual, sitting together but then no interactions...

indoors I had had only unfriendly sessions or, like the bath tub, no interactions.

I washed the grids from Deirdra's dissasembled condo and put one up in my basement. Total no-bun's land.

Last night, I furnished it, and at midnight I moved in Mops, then Deirdra and lastly, the little devil Lint. This was the first time, in an enclosed space he didn't chase or freeze. All three thoroughly explored the new dwelling. It took a while and eventually they each picked a spot for themselves to do routines... Lint and Deirdra respectively at opposite ends of the 5 by 2 by 2 grid condo. I stayed up til 3 a.m. watching them and then napped off in my makeshift  bed til 6!!! I woke up to three peaceful bunnies. (If they had founght it would have woke me.)

I will leave them like this since while they're sleeping now and then in the late afternoon it will be exercise time on the patio and then back into the condo overnight.

The great news is that I could see right away how Lint's attitude and demeanour was different than in any other location I had tried. He was more like the bunny I used to know before Deirdra came.

I'll do that! They are actually quite happy in the basement because of the cooler temp.

Lint just asked for grooms from Deirdra.

Now, if D just smartens up quick enough and gives him grooms, things will go much better and quicker then.

Most people are afraid to leave bonding bunnies somewhere 24/7 but they sometimes forget that THAT'S why they're doing the bonding.

Very well captioned!

I am just waiting for Lint to get grooms from Mops and D at the same time one day... that would be like him.

Here are some videos from last night taken during the first ten minutes of them moving into the bonding enclosure.

megrat, that's great your bun is getting neutered soon! -- but you can get a bunny other places than craigslist, right? Deirdra was originally from the meat auction.

I enhanced the bonding condo since they are going to be in it for a couple of weeks, or longer. After reading about mrmac's episode with Dexter's cage becoming the subject of a quarrel, I wanted to see how Lint would react in the neutral/shared condo if I added his old 'bathroom' cage. Lint loves that thing, and was protective over it when I bonded him to Mops. I washed it with vinegar and attached it to the outside of the condo, leaving an entrance. Maybe I shouldn't have done it so soon, but I had a good feeling. Lint chased D a few times out but then he settled and would let her be, only he doesn't want her in it while he is using it. It makes cleaning for me easy because it has a slide-out tray that I can get from the outside of the condo. Plus, it adds more room. Here's a tour of their space:

And here you can see Lint nipping Deirdra during a rough groom... I checked and there isn't anything there on her in that spot.

They do eat together in that cube. It's crowded but i thought it would bring them closer. I could change this space, make it bigger.

I definitely try to be less soft with Lint. He is jealous of D, nips at her and me when I pet her.

--Mops the barrier bunny, LOL!

But this morning I brought them fresh clover and Lint didn't care who he would get stuck beside...

And last night he even shared the litter box with D for a moment.

Lint surprised me! -- See this clip: (bear with me, it's in two parts)

in the first one it seems Deirdra doesn't trust him even though he has no bad intentions....

but then she decides to go for it...

bonding, or what?!
