I'm thinking about using electric poultry netting to win the battle against the squirrels, cats, dogs, foxes and other assorted nature in my life. I read an ad that said "poultry netting - 4 feet tall. Ideal for poultry and other assorted non-flying animals." Umm my chickens often fly up to sit on top of my coop which is about 6-7 feet off the ground. Should I bother with this netting stuf or will my chickens just jump on out whenever they feel like it. I was thinking of using it as a wide boarder around some land around my coop to keep them safer when Ilet them "free-range." But before I spend money on the netting and charger and stakes and all that I want to be sure it'd be worth it.
