A simple way to chicken (or any small animal) proof your fencing. 
Steve has a yard full of 28 chickens that are a little bit too "free range"! He often finds them on his patio and even on his pool cover. And where you find chickens, you find chicken poop. Wanting to keep his chickens away from the more livable areas, Steve used Mosquito Nets USA's 3 foot heavy duty black netting to prevent the chickens from squeezing through the fencing. 
Steve simply threaded the netting through the fencing and used tarp clips and zip ties to keep it tightly in place. 
The chickens are kept on their own side of the yard with a screen that does not impede the view and Steve can enjoy his patio without having to share!
