When I first got chickens we had a little 8'x5' outdoor coop/run area. We moved it (it was built to be moveable) to the other side of the yard inside the huge pool fenced area and made perimeter fence along 2 block walls with a "Tunnel of Doom" bench seat under a shade covered poolside patio, so they could go out under orange trees. You know what we thought was the Tunnel of Doom actually turned out to be the place they liked the 2nd best (after the 1st place- under orange trees).
Lesson I learned --Whatever you build, make it moveable, flexible, even modular or reconfigurable IF POSSIBLE.
