So I have been watching for signs of agression from Chipmunk and Hazel. they are brothers and have both become teenagers. well they have now been constantly humpin eachother, should I seperate them? they are getting fixed in a few weeks and I just dont want to break their bond.

I would separate them until after they are fixed, sounds like their hormones are well and truly raging now, in my experience humping can lead to fighting, which is obviously something you want to avoid at all costs,!!!

I wouldn't separate them unless they are fighting. If they are humping and it's not annoying either one of them. Just play it by ear and see how they react to the humping. Humping doesn't always lead to fighting...it's annoying to humans, but not always to rabbits.

there hasnt been any agression they just seem to take turns circling and who is on top lol.
