I am in the concho valley area, on top of conglomerate limestone. There is no digging of post holes, you can drill and jackhammer. But I took a more reasonable route. Neighbor has a big pile of wasting away mountain cedar (Juniper) logs. I cleaned them up with a chainsaw, and made a very large wooden frame for the poultry netting. With all the ferral cats and dogs in my area have not a lost a bird yet. Here are a few pics of my totally enclosed run and coop. Total monetary investment in this coop and run is $100. Used all reclaimed lumber, logs, and odds and end roofing materal. Only thing paid for was the chicken wire and wire staples.
