I am planning on fencing approximately 130 by 50 area of my backyard, to contain chickens, so that they do NOT eat on vegetable beds. (they are great farmers otherwise) My dilemma is this: We had plastic netting chewed through by unknown animals. Possibly squirrels. Metal mesh is simply too expensive for the project. I am fully fenced chain link on all 3 corners of the project and only need to run 130f long fence with gate run to close it. Chain link is also very expensive to use plus, tree rats will get through links anyway. I am open to suggestions on something rather not very expensive that will actually hold those small critters at bay. I am planning on 6 f tall posts, to match overall fence height. Ideas?
