We are just about ready to start work on our outdoor run. Our chickens are housed in a 8x8x8 enclosure inside our horse barn. We already have a area beside the barn that is enclosed with 4x16 livestock panels about 16x50ft I will wrap the panels with wire fence ,the smallest fence I can find is 2x4 openings. Hardware cloth is too expensive for a run this size For the top i was going place a set of poles with a board runnning between them support and string wire 12 inches on center to support deer netting. The panels are not under ground but I was going to make a 2x16 panel flat along the ground to prevent digging animals. We will have a pop door that we will close at dusk to keep the chickens inside at night. I do want to make a auto door but that will be in the future. So my question really revolves around the top covering of the netting will this prevent areial attacks or will predators climb the fence and get into the run?
