rabbits fighting???

hi i have 2 boy bunnys they are just over 8 months now and got neutered at 6 month they are both brothers and usualy get on great but yesterday when they were out in there run they started fighing was horrible to see this is the 1st time i have seen them do it and they where ok today not sure what to do if they keep it up? or why they have started this??

is their run big enough for them and have they got enough toys etc to keep them occupied?
hopefully it's just a one-off as they're ok today
i agree with you it's horrible to see

run

yes my run is around 17 feet by 6 feet so def lots off room for them they have lots off toys etc aswell might try get them a few new things etc.
