I have two bonded pairs of rabbits. My first pair, I have had for 5 years and my second pair, I adopted last year. I keep them outside so I can give them lots of room to run. Both pairs have a covered dog kennel with a hutch inside, and then they have an 18' X 18' free range area (covered with bird netting) where they can play, run and graze. I would like to be able to let both pairs out in the free range area together, but they would fight. The older pair has already established the area as theirs, so they run off the younger pair, and I know they would fight if I left them together in this area unsupervised. I made them take turns in the free range area, but my older rabbits seem stressed when they saw the young rabbits in the free range area. Is there a way to turn an already established territory into a neutral territory?
