So you have actually lost chickens to hawks? That's strange. I have as many as 15 circling here all day and they never bother mine. Have you considered attaching brightly colored strips of cloth the the black netting? Maybe they can't see it.Hello out there. I found the survey for predators and was astonished at the results. I used to have chickens, don't right now but trying to find exactly what I want. I live in a rural area and my biggest problem was with hawks. My chicken run is fenced in with black netting over top. I also have a small pond, about 8 x 10, with 3 very large koi and a dozen goldfish. I have dogs too, and inside cats. Raccoons show up here every so often but they seem to scare pretty easy. I think they can smell our dogs. They've tried to get to our fish and they've tried to get to our chickens but never made it. But the hawks were the scariest. We couldn't keep them away. They sat in trees and flew round and round. Sometimes they caught little birds that fed at the outdoor feeders. We had to stop feeding wild birds. Then we would see the hawks fly from tree to tree. In fact, around here they hop around on the ground . I've watched them with binoculars. I don't look up to find them, I look toward the ground or on low branches of the surrounding trees. These hawks winter here, they don't migrate. They're smart, lightning quick and super determined. What can I do? Can't shoot them. Tried all the suggestions from this forum. I want to keep banties and can't have a roo. (bothers the neighbors) I would like to figure this out before I do get my banties Has anyone tried that motion detector for coops? Wondering if that would work....
