Has anyone made a run that was just a rectangular cube covered on all six sides with hardware cloth, with the coop placed smack in the middle of the run? I've been thinking of creating an eight foot by ten foot run area. I'd mark off the rectangle on the ground, and then remove about six inches of earth throughout that rectangle. Then I'd simply build the cube in place so that the cube would be sitting six inches below the surrounding land. Then I'd walk into the run and and add the removed six inches of earth back into place on top of the cube's floor. Then I'd add wood shavings litter or maybe sod to the run. Seems to me that way, I'd have a completely predator-proof setup, and I could leave the coop door open all the time day and night. No need for cement, or concrete or wire aprons around the run. Just some vertical wooden posts to frame the four corners of the run; then some horizontals nailed to the verticals along the floor and along the top of the verticals. Probably would add some more vertical posts at three or four foot intervals to add more stability and rigidity to the whole thing. Seems to me it would be too big and heavy to need to set it in concrete. I'd partially cover some of the run's ceiling to provide shade and rain/snow protection. Any advice or comments about any of this? Would love to know what you think.
