I have 1 buck and 2 does currently in cages. I've been thinking about building an inclosed pen (with roof) for them to live in a community. (colony) I haven't been able to find any reliable info on the construction of a colony/ pen. Does anyone have any advice or know of any good books/ websites regarding colony life for rabbits? Thanks!
These are my breeding rabbits. Intended few as pets and others for consumption.

The buck has mated with both my does on previous occasions.
