hi there, so I have 5 indoor bunnies. 3 single boys all under 1 years old And a bonded male/female pair. I have to let my single boys out one by one to play and whenever my bonded pair see Winston they start chasing each other round their pen and almost like they are about to fight. Whenever they see the other two boys they pay no attention and are fine. Why is it when they see Winston they start scraping? It’s got to the point I have to let Winston play in another room alone because I’m terrified of my one bonded pair breaking up. Anyone have any idea why this is happening?
