on my new duck run. My run is 24'x48' and I have an arch over the the entire run. I used the left over from the long run to use on the ends. I have the same stuff over my chicken run, 16'x48' but I just have it running over the top of the fence, no arch. It keeps them in and birds out. I don't anticipate it will keep foxes or racoons out, but that is why I lock my birds up at night in their smaller secure area.
