I built a chicken enclosure for my 4 chickens that is hawk proof. The enclosure is 11 ft sq and 7 feet high. I put deer fencing on the sides and strung fishing line in a grid across the top. It's been up for a year and I have had no issues from the hawks. The frame is very sturdy with MP connectors. We have had a few terrific wind storms in south NJ. Thank you MP!!! Best wishes for your continuing success.
