Chestnut lost his wifebun recently, they had been together for around 8 years. So I decided to bring him indoors, I was a bit apprehensive as he has never been indoors, anyway he has been ok but he does seem to be a bit lost. He's in an enclosure next to 2 other rabbits. I have 2 options or 3 really, 1 to try and bond him with 2 other fairly elderly buns in the next door but one enclosure (in a neutral space), 2 take a 7 yr old from a group who have been together all their lives, or 3 keep him on his own. What does anyone think - he is 9 nine and I don't have a single female of around that age?
