I am currently using this method and it has failed miserably. The wind is so vicious where I live, it just whips them all around and tears them apart. I plan to switch to something rigid like clear corrugated plastic that I used for their roofing in the run.I plan to use clear tarps with grommets on the north and east side. I don't know how well it will work. But I'm trying to keep it nice for my chickens and ducks.
