A couple of points to put your mind a bit more at ease:
- No matter what happens during her date sessions, Sophie will not love you any less. Rabbits are social animals that live amongst large numbers of other rabbits in close quarters. Their instincts are to interact with large numbers of other animals. She will not forget you if she gets a boy friend, or blame you if she doesn't.
- Almost nothing you do will effect the choice of a buddy for Sophie. She will choose who she likes; your job is to facilitate the bond. You cannot 'make' her like somebun or 'make' her hate somebun, she will decide for herself. Don't fall in love with any of the boys, because that one will be the one that
she hates
- Some buns just don't like partners; Gravehearted has one that just really likes being an only bun. Such buns are rare but not unheard of, Sophie could be one of those.
- You'll know right away if she does not like somebun (growling, circling, boxing, biting). Determining if she is interested is a little harder. Boys like to mount; make sure that she is not uncomfortable if this happens. Do not allow mounting from the front! She could bite the other bun in a most uncomfortable spot. Good signs to look for are her presenting herself for grooming (stretched neck, chin on the floor), sharing a litterbox, sitting close together but ignoring each other. She may also nuzzle the other bun or groom him. Be prepared to intervene if either bun appears stressed, and use a towel or gloves to separate them, lest you get bitten in the mele.
- Taking her to a place outside of her comfort zone is a really, really good idea. She has no territory to defend there, and will be a little scared, which makes her more receptive to making friends with stranger buns.
As to her not being around other buns much, she'll figure it out. Instinct is a powerful thing. Please try to have fun with it. The process can be long, but it is fascinating to watch. If she does like somebun, then you have to decide if you want to wait and try another date, or bring the other bun home and work on the pairing right away. For most pairs, there is still a process of cementing the bond once the dates go well, which will require that you house them separately when you are not with them until you are certain that they will not fight in your absence.
Good Luck and let us know how it goes!
