I think that netting would definitely work across a run. I'm sorry to hear about your losses.
I have netting hung across about 1/4 of my backyard, which has about 8000SF of space chickens who free range from dawn to dusk. My net is not as robust as the net in your link. Mine is just regular bird or deer netting. We have many resident and migratory Hawks in the area. They've attempted many attacks on my chickens. However, thus far, the net has helped deter them and has bought my chickens valuable 3-10 seconds of time to hide. We've had many close calls recently. I think the hawks have found the weakest point from which they can start their attack. We're planting some more vegetation in those areas. I could also hangz more netting, but I also want local wild birds, hummingbirds and insects to be able to visit the garden. I also know it's a game of probability and one day I will lose a chicken to a hawk. However, it's a risk I'm willing to take after weighing many factors.
