I gave into the kids a couple of years ago and we took on an English Old Spot rabbit who was an 'adoptee' from Pets at Home.
The store told me that he was up for adoption because he fought with the owners other rabbits and that he'd never be able to live with another rabbit.
We got him home, set up his hutch and a small run area (about 5 feet by 3 feet) that we could move around the garden onto fresh grass.
It soon became clear that he was lonely but the store had told us he couldn't be introduced to other rabbits because of his history but we read up and found out how to introduce rabbits to each other.
We followed the advice and after having him neuterred we set up a separate run next to Shaun where he and Sally, another adoptee rabbit, could see each other but not actually touch. They were supposed to be like this for up to 3 weeks whilst they got used to each other, and the sign that they had accepted each other was that they would lie alongside each other in their own runs with the fencing separating them... they did this from day 1!
After a few days it was clear that they were happy together so increased the run size to accommodate both of them (by this time they had 1/3 of the 15 metres by 10 metres grassed garden) and soon after that they ended up with the entire garden!!!
Clearly, the family that had Shaun first didn't introduce him properly to the other rabbits and so a stranger had just been thrown into an established group and it caused horrible tension. Sally was also from Pets at Home and I think that she had been neglected and very likely chased around the garden by a previous families young child or other pet because she is so nervous and can't be picked up.
They are, however, the happiest bunnies I have ever seen and I'm so pleased we were able to give them such a good life together :happy:
