We had a free-ranging flock until two weeks ago, after two unsuccessful hawk attacks on two of our hens and then a disappearing guinea cock. Reluctantly we put up a 6-ft-tall fence, approximately 33yd x 12yd (not feet). There is good foliage and tree cover for the flock to hide in. We strung a grid of fishing line over the entire area and attached plastic bags and ties. Our last guinea hen got out last week and a hawk tried to get her, again unsuccessfully, but we added more fishing line in a few more areas right outside the run. Today, we walked out to a Cooper hawk feasting on our kids' favorite white bantam, very close to the coop. For such a large area, how can we better protect them? The fishing line obviously didn't work. I've read about putting chicken wire completely over the top of the fenced in area, but I can't imagine doing that for such a large area. But is that basically what we have to do? I know hawks will only stop coming when there are no more chickens and we don't want to watch our flock get picked off one-by-one. Also, and kind of an aside, I feel like our alpha rooster was a better protector of his flock when they were free-ranging. He fought the hawk off 2 of the 3 unsuccessful times. Or maybe I'm just reading too much into things. Any help is much appreciated as we have limited time. The hawk has already been back to try and find any leftovers from the clean up and has been flying around the property all day. Thanks!!
