Netting was the way to go for us. We are in Hawaii on the big Island and have only two winged predators, Barn owls and the native Io. Neither have been a problem for us since we put in aviary netting to cover the 20' x 20' run. It has 2"x 2" and made from squares polyethylene that so far has lasted three years for us. Good luck with your solution, keep us posted on what you end up with.Was just reading and came across this post, so you just need something to deter hawks? don't actually need a net? We had some issues with a hawk during the winter and tried closing it in but since our run was an odd shape it is an eye sore. Something like this would be so much easier on the eyes.
