I have had great success with forming a grid of Mason Twine across the top of my run. My run is 6' tall and 28'x35' so it took a LOT of twine, but works well. I heard commotion from the hens one morning and went out to see a hawk sitting on the top of the fence with no way to get in to the hens....he was frustrated, I was angry, I won! The grid is run about every 8"-12" over the entire run.
hope this helps!!

Mean time the heat and humidity made us rethink the coop a bit and it now has a 12' x 16' covered addition(chicken patio?LOL) to keep the afternoon sun from shining in one of the windows and heating it so badly. it is actually a tarp but we framed it up with 2 x 4's so it is sturdy. Now reviewing whether we want to continue with this and make this a permanent covered but open section on the coop. I will try to get a pic tomorrow if it will load on here.
