I am trying my hardest to predator proof my chicken pen. The pen is like 40x30. I am wondering what is the cheapest, yet safest way to cover to top. It still needs to allow the 2 single gates and the double gate to open. This is where I get messed up. They all open into the run, so I am unsure. I was thinking of removing the decoration over the top and useing 2x4's to prace it. Does this make sense or will it be okay with out it. I was thinking of using deernetting
