I had 2" mesh aviary netting installed over my daylight run, which is fenced with 48" posts. Walking in the run was a chore, and the 25'x25' netting stretched more than the 25'x25' dimensions of the run. On a cruise through Home Depot, I found 3/4" diameter 10' sections of plastic conduit for only $1.05 each, and an idea hit me. I bought $10 worth of conduit and some cable ties and went to work. See the results in the photo. The conduit joins together just like light weight tent rods, and just like tent rods, can form a framework under the aviary netting. The cable ties are used to keep the framework from moving, and the center of the framework is hoisted to a suspension rope between two trees. It would stand without the center support, but this support adds stability in case of high wind. I can now walk easily everywhere in the day run, and the hens seem to enjoy the higher perch, which is just high enough so that my big, fat rooster can't get to it, but they can. Although the aviary fence is electrified and dug down !8", it's still for day use only, the coop and covered run to the left in the photo are more heavily "armored" and seem to be predator proof day and night. As you might guess from the photo, we have raccoons, possum, fox, dogs, hawks, snakes and vermin to contend with in this location.
