We had a really close encounter with a red tail hawk that much have had a 5' wingspan. Not only did he not care that I was standing 15' from where he dive bombed the chickens, he also didn't seem to care that I took off running towards him and screaming obscenities that would make a sailor uncomfortable. He hit the fence line and then proceeded to try to snatch a chicken....thankfully our rooster was attempted to fight him off when I reached them. The hawk took off, circled a few times and then left, probably in search of an easier target. I know that this is all part of owning free range chickens, and for the most part, they keep a close eye on the sky but yesterday left me with a pounding heart and bile in my throat. I want to keep them safe, so I started researching hawk behavior and ways to possibly deter them. All I found was information on CDs, scare tape, fake owls, installing speakers to play owl noises or crows in distress, oh and to remove the food source [chickens]. I also read that the hawks are easily spooked and don't like change [though if the hawk is hungry enough, the above points are all moot] I feel bad cooping them up, and I can't sit outside all day and watch the skies for them, though I do peek out the window religiously during the day and go outside to check on them or give them treats. My problem is, I don't have enough tree cover; the yard is fenced in, butu completely open. This summer, I'm planning on putting some trees and grapevines in the yard to kind of make it more difficult for hawks to have a clear landing strip....but for right now I'm kind of up the creek. This morning, I had my neighbors two miniature horses come over....I'm hoping that the two big, constantly moving objects in the back yard will be enough movement and change to keep the hawks at bay. I've only had two instances where hawks actually landed in my yard, the first time the hawk was much smaller and he couldn't get into the chick run, so he sat on top of it calling his friends for backup, I assume. And yesterday, where the butt face actually dive bombed the flock. Does anyone else have ideas that have worked for them in the past? I'm going to try to put some aluminum pans out there, but mirrors are a little too expensive to just lay out in the backyard.
