Since you guys were so helpful on my other post, and my shed is slated to arrive this Mon., I figured I'd ask about run construction. My plan is to make the run 10' long x 7' wide x 6' tall using "panels" made from 2x4's and wire that will attach (naturally) to the shed/coop. I also plan to dig a trench around the run and place landscape timbers in the trench, run the hardware cloth from the run walls to the timbers, attach the cloth to the timbers, then add in rocks and backfill over that with dirt to (hopefully) deter digging predators. We're going to use landscaping sand--the kind with rocks that the chicks can use for grit--with DE and wood ash mixed in for the run flooring. My questions are: 1.) Is that size big enough for 5 chickens (with possibly a few more additions down the road)? 2.) Can I use 1/2" hardware cloth for the lower half 3' down and either poultry fencing or 2"x4" welded wire for the upper 3' half? Or should we use 1/2" hardware cloth from top to bottom? We do have foxes, raccoons, skunks, possum, and fishers here, plus probably coyotes (although I haven't seen any yet).
