I have the bird netting but was thinking the high strength DEER netting might be just as good as the wire fencing.I think both might be same in cost.
Bird netting is better than nothing,but eventually the hawk will get through it! CDs,fishing line,and T posts can affect the flight of the hawk as it comes down onto the chicken,but again not 100%. Only the enclosed run is a sure bet.Red mylar ribbon is used too.Some fake owls. Encouraging blue jays or other birds that will swarm the hawk.Oh and bottle rockets.
