Hi
I've successfully bonded 2 bunnies recently. i think thekeyword is perseverance - don't give up on trying. I followedthe Miriams Bunny Post mainly but I altered a few things.
My bunnies are mainly outdoor. They sleep in hutches in thegarage at night but the rest of the time they have a big completelyclosed-in run which they're out in every day - it has 2 little huts init and a covered area for shelter. Anyway, the run wasdivided into 2 with chicken wire, we put one bun in one side and one inthe other. Benjamin was already established in the runa ndtherefore saw the entire thing as his territory, when the new bun camealong he was very interetsed - he would grunt through the chicken wireand launch himself at it in attack. The mew bun was veryinterested in him too although she wasn't vicious towards him, shewould poke her nose through the bars to get a sniff of him.After about 8 days of keeping them half and half I put a towel in thebathtub and brought the buns in the house - one at each end of thetub. The 1st time Benjamin went on the attack - he was tryingto hump Twinkle even though they have both been 'done', I left themtogether for about 10 minutes and then seperated them. Thesecond day Benjamin was calmer and didn't attack as much - they stayedin the tub for about 30 minutes. The next day they sat in thetub and ignored each other and stayed there 70 minutes. After5 days of that I let them roam the dining room and they were tolerantof one another - no humping and no fighting. I kept doingthat every day for the next 5 days but was always careful to watch themclosely. After that 5 days I first saw them sitting togetherand grooming each other. After another 5 days I removed thechicken wire down the centre of the run and they were fully bonded.
They are now the most in love couple you could imagine and follow each other everywhere.
I think the key is to introduce very slowly, if the fighting beginsjust persevere and stay on that step of the bond a little longer - keepmaking them see and smell each other.
Some rabbit's don't bond - no matter how much you try, ultimately it'syour bunnies choice whether they want tobe friends but I'venever known a bunny choose to be lonely and on his own rather thanhaving a companion.
