I have four rabbits, Douglas, Bobby, Joey and Boo.
Both pairs are male and female and all are neutered and spayed.
I have bonded in the past and I am pretty confident with the rabbit body language but Joey is constantly on the defense and whenever Bobby or Douglas go near him he attacks and then they start fighting. This also happens when he goes over to them as well. Boo is the most submissive out of all of them and she has already started cleaning the other two but the main problem is that Joey is very aggressive and even attacks Boo (his bonded partner).
Today I did a stress bonding session though I really didn’t want to because I don’t like putting too much stress on the buns, especially Bobby who is already very timid. Anyway, although it seemed to work with Boo and she seems to have become quite close with Bobby; Joey is still being aggressive.

Was looking for some advice on the situation as I’m beginning to lose hope with the bond.
Thank you so much!
