My secure-I-hope coop will be inside a dog enclosure run which has two walls made of a stone foundation and the other two are metal fencing. Height of run is uneven but ranges from 5-6 feet. We are in the mountains in a secluded area. Hens will be put inside coop every night, but for the daytime, I know I need to cover the run and wonder if chicken wire would be strong enough to keep hawks out? The hardware cloth is prohibitively expensive; aren't there any alternatives? I have a friend whose enclosure was topped by the green plastic fencing, and a hawk just dive-bombed right through it to make his kill. ( Hawk was then unable to fly out of the run.) Do I only have to worry about predators at night, or are the chickens constantly in danger?
