I love my free range chickens, but my wife loves her gardens, so we've come to the agreement to split our acre long yard down the middle, with my birds out back an her flowers closer to the house. Problem is, my hens are strong flyers, and can easily jump the five foot wooden fence dividing the yard. My wife doesn't want to raise the fence as she thinks it will look ugly, and I agree. I've tried clipping their wings, but they somehow still manage to get over. Is there any other way to keep my black sexlinks on their side of the fence without raising it?
