I live on 10 acres and over half of it is wooded. I have had the occasional red-tail hawk attack on my big roo but he's been either extremely lucky or he's tougher than he looks!
I let my 2 hens and the rooster free range only a couple times a week and never for 2 days in a row, just in case the attacking hawk comes back the next day looking for a free meal again. The rest of the time they are in a 20' x 20' run that is half covered with a white tarp and the other half with golf netting. I've had the golf netting up for almost 2 years and it's not rotted yet, only one or two places where a squirrel has chewed thru it to get down into the run and help eat the Cheerios and other goodies thrown inside.
