I have a friend that keeps the chickens out of his wife's flowers, he uses the woven tape instead of the wire for his purpose he places the tape at about 18". Also does a good job on the dogs and cat. I'm thinking the tape would work good as chickens love to perch on fences, perching on the tape would be like a logger trying to stand on a log in a lake. Maybe you don't even need to energize it. Maybe place the tape a few inches higher and about 6" inside of the fence, a few upside-downers might deter them from trying again. We have had the invisible fence for our dogs off fo months but they stir stay in the boundry.
