Sorry, Tazy. I can’t open the link and it doesn’t find it when I copy & paste.
Be careful of using the term “aggressor” when describing bunnies. I have a bad habit of doing it but the aggressive bunny is typically the one that is more fearful. Recent studies have shown that rabbits are not aggressive animals and that their aggression is stimulated by fear. The “aggressor” is usually showing aggression because he does not trust the other rabbit – not necessarily because he wants to be dominant or does not like the other one.
The dominant role can actually change quite a bit, it does not necessarily stay the same rabbit. I have a pair, Simba & Lacey, and you can tell from watching them that the role changes from rabbit to rabbit quite a bit. However, in my larger group, my boy Fleury has always been the most dominant in the group. His reactions kind of speak for themselves though – when anyone in the group bickers, he will intervene w/ his ears back and tail up and lunge at both until they stop. And then he will continue sleeping from his perch on the box in their area. Haha!
