My gf has lost two hens to a hawk; the one a few days ago was the star of the flock, her favorite. Supreme bummer. I think it was a Cooper's Hawk, I did see it. They are medium size and very agile flyers even in the woods. Not big enough to carry a hen away, they have to eat it where killed. It sucks but it's part of nature and life. However, we can't stand this happening again. We can't stand to keep the hens cooped up all the time, so, for a long time, we have let them free range outside the coop into the very large run. The entire run or chicken yard, which surrounds the coop with fencing that is about 6-7 feet tall, and the total dimensions are probably 50' x 150' -- it's large. Too large to cover, it would cost way too much, I did an estimate. So, now we are considering making a covered area surrounding the coop, reducing the dimensions of the run / covered chicken yard. But, how to build? For a cover, I have seen people mention deer netting, fruit tree netting, poultry netting. Does anyone have an opinion on what type of netting? I could use chicken wire but it would be too heavy and cumbersome. Whatever netting is installed, I don't think it could be 'flimsy,' as there are large trees right above/surrounding the coop and some small limbs could fall from time to time. Beyond that, what type of fence posts and framing would work? I would think the fence posts would need to be maybe 8 feet tall to allow for some droop. Might need to install a few fence posts in the middle for support. Tall 2x4s, I wonder if those would work for fence posts? Would they rot in the ground too quickly? Another problem is the large trees. I would prefer to go around them with the netting but I don't know how we are going to pull that off. Might have to just make the covered part smaller and stop it at the base of each tree. Anyone have an idea how to build a cover? Anyone found a good deterrent for hawks?
