Rabbits fighting

by Gabrielle
(Scotland)

Hi, I need some advice, I have a bonded pair of 1 year old male neutered rabbits.

Recently they have been fighting sometimes quite badly. The smaller one, Apollo, prefers being in a pair whereas I doubt the other, Cornelius, would mind being on his own.

I also have another rabbit, Carter, but him and Apollo don't get on either. I don't know whether I should seperate Cornelius and Apollo or not...at what point is it not fair to them to keep them together any longer?

Help please
