I'm thinking a 6x4x4 box with a 2ft tall run underneath. This will give me the height to provide proper roosts, covered nesting boxes, and feed/water dispensers. They have to stay caged 24/7. I don't care about their feelings, health and sanitation are the priorities. I can't do a tractor because I need to keep them generally out of sight, plus it'd be better to plan on predators.
For reference this is the underside of the shed, you can see the back of the current coop.
