Breeding rabbits.........?

[amyb]

I have 2 rabbits a male and female when they where young they used to sleep in the same hutch stay in the same run and everything but one day we went outside to find them sat at opposite ends of the run with fur all over and they both had to have stitches when we told vet he said that it might have just been hormones so we tried them together again a few months ago but they went straight for each other, so we kept them apart, a few weeks ago we tried them again and after a bit they just went straight for each other again, my mum's friend said that when it gets a bit warmer maybe towards the end of march they might calm down as it is breeding season, we really want babies from them but don't know if they will breed because of the fights...............
thanks for any help
