Rabbits will start fighting once they become mature. Some younger does can be housed together but not always. I would keep them seperate.
I let my chcickens and ducks free range in my barn with the rabbits. The rabbits are all in hung cages off the floor. The chcikens and ducks do a great job cleaning up any spilled feed. I also keep hay on top of my cages. This gives the rabbits something to do as they will pull down hay to eat. It also helps to keep chicken manure from getting on the cages if they decide to roost on them. It is very easy to discard the yucky hay and keep the cages clean.
As far as not breeding till spring. Unless the does are to young you are risking them getting to fat not keeping them on a regular breeding schedule and then when you do try to breed may have problems. I breed my does at 5 months and they are consistently bred back 11 days after kindle. Doing this intensive breed back will give you about 2 years on each doe and then you need to have replacements ready. Good record keeping is a must.
