Any bond that may come between a young rabbit to another rabbit, regardless of that other rabbit’s age, may be seen as temporary. By young rabbit, I mean one who is has not reached an appropriate age to be neutered/spayed. Rabbit bonds established before hormones develop likely to suddenly change once hormones come in, making that rabbit act on mating and territorial urges. Most likely, any baby rabbit would initially try and get along with your fixed rabbit; however, when they grow and experience hormones, this will change. Also, your rabbit may act on territorial urges due to a new rabbit’s presence, even if he is neutered.
The best recommendation I can give is adopting an already fixed rabbit and going through the bonding process with your rabbit. You can find information on bonding rabbits in the RABBIT INFO section of this website.
