This Poultry Netting is a 48" electrifiable prefabricated fence with 12 horizontal lines and is 164' long. White vertical lines are welded to black and white electro-plastic horizontal lines supported by 1/2" diameter white PVC posts spaced every 8' and there are double 6" spikes on each post for support. Keeps in poultry, sheep, goats and cattle (except baby chicks small enough to crawl through openings). Just attach a fence energizer and it's ready to keep poultry in and their predators out. One roll weighs only 23 lbs.
