I have been very lucky not to lose chickens to the hawks in our area. (Knock on wood). I was reluctant to let my chickens free range but an old farmer friend told me to just make sure to have plenty of good cover. I have only had chickens for a year and a half...but wanted to share a few ways I think I have provided good cheap cover for my chickens. We have a TON of hawks here...red-tailed and coopers. They are EVERYWHERE. I sometimes hear the hawks screetching in frustration VERY near my chicken area. More cheap ideas would be great!!!!!! I have a raised bed that I planted thick with blackberry and rasberry bushes. Most of the plants I dug up at the edge of the woods. Then I added a good two feet of cheap mulch. The chickens have dug out underneath the bushes and created little caves for themselves under the blackberries. I can't even pull them out of there! I wouldn't think you would have to have a raised bed....any berry patch will do! Here is the blackberry bed...two years ago. Now it is just all crazy brambles. And I have since added deer netting behind the grapevine trellis. I also planted two mulberry bushes three years ago. Mid-day, especially when it's hot out, I will find chickens stashing themselves under the mulberry bushes . The mulberry bushes were like 18 inches when I got them in the mail...very cheap! In just three years they are the size in the picture below. Also in the picture next to the fence are tiger lilies. They grow by the side of the road here...everywhere. So I just dug a garbage bag full up and planted them all along my fence lines. The chickens dig and dig and they can't kill those plants! The chickens hide in the base of the lilies.
