None of my current buns (group of 4) are as loved up as my previous pair (never found one more than 3 metres from the other). That pair fell in love after about 5 seconds.
With my current bunch:
Stuart has lived alone for a long time and I think he is only slowly learning how to cuddle. After three months of living in a group I saw him two days ago, for the first time, choose to sit next to another rabbit. This has not been repeated yet.
Crackers is bullied by Stuart but knows not to get too close. They are slowly decreasing the distance that they can tolerate between them. This is the best I am expecting.
Bluebell bullies Laikin in a small way.
None of them cuddle for hours, lying with their heads together, but they do interact and give each other half-hearted head licks. Just like people I suppose - some are demonstrative and know that they need love, others just hang around with friends and accept what comes without demanding more.
