I would recommend separating them immediately, at their age they don’t actually bond and can get into a very nasty fight when hormones kick in. You also run the risk of one of them being female and getting pregnant.

Most baby bunnies love to groom other bunnies which makes people think they are bonded when they aren’t.

They are not bonded. Baby bunnies can make friend but they don’t bond. They should’ve been kept separate after that first fight. They aren’t dogs and cats where you can just put them together and they’ll have little tussles once in a while. Bunnies are territorial and can fight to the death. Separate them immediately, especially now that one is humping the other.

Contrary to what some people believe, bunnies do not establish dominance by fighting. They establish dominance by humping, and sometimes a little chasing and nipping. Fighting should always be stopped as bunnies can fight to the death.

As yours are at an age where hormones are at play, they must separated. Once they’ve both been neutered and their hormones have dissipated, you can start the bonding process If you are unsure of the bonding process, check out the bonding section of the forum and feel free to start your own bonding thread when the time comes so we can help. It might also be worthwhile having a read of some of our member’s bonding journals so you get a rough idea.
