Just how do you get chicken wire tight? I have strung it between coops and pulled as hard as I dared but it winds up looking saggy. How do you pull it tight and not make it look saggy? Do you run a pole down the side of it and pull for equal leverage? We did that with hog wire and dog wire but I didn't think it would work with the flimsy chicken wire. We are about to start another coop and it will have several divided coops inside so we want it to look good. Thanks! You guys are always so smart about this stuff!
