THE CHUNNEL! Suburban or urban homesteading and farm. Our chickens in their DIY chicken run tunnel. We live in a residential area, so to keep the chickens protected from hawks, dogs and other predators (and to keep them out of our neighbor's yard) we hook up their portable play-pen to the run and let them range. Easily crafted from 2" welded wire fencing, cut to 54" length and sod staples to anchored to the ground, and dollar store zip ties to hold the sections together.
