To keep Hawks and even larger birds of prey from taking our laying hens we suspended Deer netting over the top of our new Chicken run. To keep Raccoons from climbing down from the barn roof and into the run there is a couple foot space between the roof and netting. To support the netting I wove 3/8th inch fiber glass electric fence posts into the net and supported them with steel wire to the side of the barn. We took every precaution we could think of to keep our layers safe from predators.
