Bonding a third bunny

Hi all
I need your advice how easy is it to bond a third bun to a existing bonded pair my pair are male and female and the one i would bond is male all are neutered would this be as straight forward as my pair were or would the males be harder thanx xx

It will be as straight forward or as complicated as the bunnies allow it to be. You also need to make sure you are adding a third for the right reason (i.e. for the benefit of all three bunnies) and ideally, adding a bunny that works for both in the pair.
