We have 2 colonies. One is 10x16 and houses 4 does and a buck. The other colony is 20x26 and houses 5 does and a buck. Both colonies are on concrete floors which makes them easy to clean out and sterilize as necessary. The larger colony has rubber conveyor belt on the walls and the other colony we had to use roofing tin on the walls because the buns were chewing on the conveyor belt....not good. Rabbits do their thing at their own pace. I have found that having a good number of does gives them a break and they tend to kindle in cycles. They keep cooler in the summers, but still tend to take a summer break from having babies. It is much easier to take care of all the rabbits since it is just two spaces to put feed and water. I deep bed in the winter and do a big clean out and scrub down in the spring, then for the summer I lightly bed it so they have some bare spots (they like to stretch out on a cool patch of concrete in the heat of the day). During the summer I keep shavings in the potty areas and clean those out once a week. At the same time I sweep any pellets on the bare floor area and clean out any dirty bedding. We like having the colonies and the buns seems very happy too. If you have any questions feel free to ask. Also, the building of our first colony is somewhere on my blog under rabbits, complete with pictures.
