I tried and they always fight. I've been breeding rabbits for 4 years and I have all my females in separate cages. And you always bring the females to the males. If one as too many babies and the other less, you can switch some to the one that has less babies. Also, you can keep the babies together after a month (they should eat hay and pellets at one month old). As soon as I see them eat, I separate them from the mother. I put them all together in one big cages or on the floor. You can breed the female again 45 days after she gave birth. The babies come at aabout 31 or 32 days. Mine almost always do at 31 days. If you need more info, those hesitate to email me.

Hope it helps!
