We live on 5 acres, our neighbors have 20+ acres. So we are not right next to each other. Our 7 free-range chickens (1 rooster and 6 hens) have discovered their beautiful rose garden. Of course, they are very unhappy and asking to us to fence them. We do not want to do that if at all possible. We love watching them roam on our land. Anyone have suggestions to keep them out of their rose garden. Right now, we are looking at ultrasonic sensors but not sure they'll work.
