Oh Dloooowan! Paging Dr. Dlowan!
While we're waiting for Ms. Bunny to arrive with her wisdom, I can tell you that when I was a kid (many decades ago) we had lots of rabbits. We built wooden cages for them that had chicken wire flooring covered with hay. At night they stayed in their cages, during the day they roamed our backyard along with all our other animals: cats, dogs, chickens, ducks, turtles and anything else that wandered into the yard. They were all raised together and never bothered each other, in fact people used to call our house the Funny Farm.
If either of our cats or dogs had babies, and there were baby rabbits around, kittens, puppies and bunnies played with each other in the yard. If it was cold, they all cuddled up together in one big pile of furry and feathered animals to stay warm. Sometimes when mom and dad weren't looking, we let them all into the house and they had races up and down the hallways.
We gave the rabbits alfalfa pellets and veggie scraps. They also ate a lot of food from the cat and dog food dishes.
Just make sure they have plenty of fresh water, a place to keep warm when cold and cool when hot. Keep their cages clean, and have a separate cage for each rabbit. Males especially will need their own cage. They don't get along well with other rabbits for any length of time and when they are getting along, the results are usually more rabbits.
