Bonded Rabbits Fighting

[boobear2010]

Hello, really need some advice here. I have 3 wonderful rabbits at home, but recently two of them have begun fighting each other. More so one of them is acting aggressively toward the other, setting off a chain reaction. All the rabbits are female and have been spayed, for over 1 year now, and these buns have been living together for over 2 years. I am not sure how to stop them. I have tried stress bonding them on a washing machine, promoting grooming, and spraying the aggressive one with water. Help!

How long has it been going on? I'm wondering if perhaps one of your females might be experiencing a false pregnancy and is therefore acting aggressive to the others because of it. Otherwise, I'm afraid I haven't got a clue.

It has been on for about 2 weeks or so now. The attacking rabbit has actually had a false pregnancy before, but this behavior did not happen back then. I've had to separate them because the second rabbit is getting stressed out. The other two want to be with her, and even alternate between asking for grooming and grooming her, but she still gets nasty
