I would have them live in a giant mansion-coop: it would have 3 floors. there would be a lighting system and an automatic feeder and waterer on each floor. every week i would take them out to free-range in the yard while the auto cleaner cleaned it all out.
the first floor: would be 8 ft. by 12ft. it would be a hardware cloth run with 4 feet of bedding in the ground. there would be a ramp up to the second and third floor, compete with sticks so my silkies could get up easily. there would be a safe, always accessible, long tunnel of hardware cloth that ran along a berry patch, and at the end there would be a pond (with covering, i don want a repeat of the KindaFarmGal's experience) and it would have coi or maybe an octopus just for me
the second: would be 5ft. by 12ft. it would be nesting areas with curtains between the boxes. it would also have windows. on the other side there would be a hole for a small, yet sturdy tree to be growing. however it would have hardware cloth around the space where it reached the second floor.
the third: a hardware cloth box, basically. hardware cloth on all sides, including ceiling. here it would have sticks of all sizes and a lot of toys including a swing and a music box to keep them from squawking.
As you can tell, i have big plans for my chickens
