Fighting Rabbits

[beanebabe]

I have 2 female rabbits, both approx. 7 motnhs old. They were spayed 4 weeks ago to stop all the unlady like behaviour and a bit of fighting. They have always lived together and they are usually loving to each other and inseparable. A few of days ago they had a terrible fight in their cage resulting in one having a chunk taken out of her ear. I have kept them separate other than a couple of times I have let them in the garden together only for them to launch at each other again. Are their hormones likely to still be playing a part in their behaviour or do you think this is the way they are going to carry on. I will have to get rid of one if it is and risk breaking one of my kids hearts, it would be a hard choice because they are both sweet in their own ways. I never thought rabbits would be such hard work. Help!
