Bonding with a third bunny is a little more complicated. The dynamics are totally different. Hef and Holly's whole life as been turned upside down. And poor Jude just wants to be friends. It's taken more time with this bonding experience, but I know it will be worth it.
During the evening, Huz and I (or just me if he's at work) will open up the Buns' hutch doors and sit on the kitchen floor. When they're ready, they come out and walk around, come get a treat from us (usually some cilantro, or a grape, or a piece of dried apple or banana) and run around the kitchen. Well, Hef will run around. Queen Holly doesn't even want to leave her bed sometimes. Actually, I give her credit. She's been coming out to play more often. And Jude will explore a little, and then then come sit on my lap. Then, get brave again, go out and explore a little bit more, and then come back and lie next to me. It's adorable.
So, through these carefully monitored playtimes, we've made some progress. Hef (the most dominant bunny) no longer snaps at or chases Jude. He will sniff her, lounge next to her, and I even caught him licking her fur once! (but I think it might have been because she dribbled some grape juice on it by accident ::shrugs::) Jude is very careful around him, and will approach him gently, sniff at him, and attempt a little cuddle. But if he moves or she hears him make any noise, she'll run like hell. Sometimes, one of them will accidently make a quick movement, which will startle the second one and make him/her jump back quickly, which makes the first one freak out and run.... and they both end up running in opposite directions at top speed over nothing. I'm glad they're getting to know each other, and neither is outright attacking. I choose to see it as a positive sign.
Now, Jude's attempts to win over Holly have not been as successful. Holly has always been very shy and timid. But, with a new girl hanging around, we've seen that she can get a little aggressive as well. If Jude comes near her, or her house, she'll try to bite her fur. Jude immediately runs away. I've kept a really close eye on those two, and won't leave them alone together. I'm hoping that eventually, Holly will get used to Jude and they will all get along so well that we can keep them in one hutch.
This pic was taken yesterday. They were distracted by some yummy cilantro and forgot to be suspicious of each other for a minute.
Recently, they got the little girl a $1K "designer" breed puppy, and the little girl lost interest in the bunny. They were going to go and "release" him in a local park (so not the best idea for a tame rabbit. He wouldn't even begin to know how to survive.) Huz and I took him in and are calling him Jude. We're going to try to find a fabulous home for him.
He is really a sweetheart. In just the few hours he's been here, he's starting to relax and become a bit more outgoing and curious. He loves to be pet on the head, tolerates being picked up pretty well, and likes playing with toys. That was fun for me to see, because my buns usually don't give a crap about toys (they have about a million of them, the spoiled brats! lol) He's a burrower, so he has a little t-shirt that he digs and rearanges. It's super cute. 
It's so funny to see another example of how different bunnies' personalities can be! If you don't own a rabbit, it can seem like they'd all be the same (kind of what I would think about fish, because I don't have them). But, they really are different and have different interests, preferences, dislikes, favorite snacks and habits.
My little Holly is a sweet, shy, timid little girl. She prefers to stay close to home, but will go anywhere Hef is. She is absolutely in love with him. When she gets scared or nervous, she covers her face in his fur. She gladly accepts any treat offered, and then runs over to enjoy it in her favorite spot- her bed (a girl after my own heart lol).
