Hi i am new here, haven't made my intro yet but thought i would chime in on this topic.
They do not deture hawks at my place, i have one that turns its head,kinda spooky looking but the hawks perch on my fence above my chicks right across from the owl.
We had hawks migrating right over my place by the hundreds, the local hawks were flying every where around my place right above my babies, i took some photos of them, i was freeking out, nothing i could have done if they decided to come in for dinner, there were to many, but my dog got to barking and the gradualy flew away, but this has happend 3 times in the last week.
A good dog,fishing line and a pack of guineas that hang with the babies help me keep my babies from becomming a chicken nuget for a hawk, i deal with them every day,
on a good note they never mess with my grown birds,but then i have alot of land for the hawks to hunt for other prey.
here are the local hawks over my chick pen, these were scaring everything ,everyone ran for cover.
here are some of the migrating ones passing over my farm like right over the house, they would swirl around in a circle then regroop and fly on by freeked me out till i figured out what was going on,they usually follow a path down by the coast but i figure sence our last hurrican changed the coast line they are a bit throwed off
