Personally I think that’s plenty of time to get her bonded to somebunny. Also, really good timing in hers & your life to get a friend if you will be busier with college (?) and the only human in the household. I would try bunny dating with her…more so to guage how she goes with other rabbits but also to socialise her in general. i.e not necessarily her picking a mate right away – just learning and experiencing.
I do have a little experience bonding a bonding solitary bun (not so submissive). I didn’t think Jersey was really seeking other bunny company to tell the truth. I got the usual bonding scenarios and antics (poop/pee, aggression, nipping etc) but they bonded in exactly 30 days.
btw there’s a little brown baby bunny in Giulys thread – did you see? Every time I see it I think of you and Binkles – though you might not! tehe. Anyway, it’s a baby and complicated I guess – but super cute to look at!
