I was very disturbed to see a raptor fly over my garage a couple weeks ago that I knew wasn't a Red-tailed Hawk. It was a slate/bluish grey color with a darker wedge-shaped tail. My wife saw this same hawk on a couple of other occasions. This morning, my father was over and saw it swoop onto a low limb of a swamp maple that stands between our property and that of the neighbor. It was after a black squirrel which it did not get. Unfortunately I have several squirrel nests around my house. Thus far I have not seen evidence of the Cooper's paying any attention to my chickens but I also realize that that means nothing. I have a very secure run/coop that I will be securing still more. I am much more concerned about when they free range. A couple weeks ago I was out with my son in the yard and the chickens were out. We were about 30' away when the girls bolted about 10-12' and were very startled. A split second before they ran we heard a **thump-whoosh** sound but saw NOTHING. We searched the skies for evidence of a raptor but saw nothing. I am wondering more and more if this was an attempt by the Cooper's that happened so fast we just didn't see it. It scared the paste out of my girls...whatever it was! I have heard many accounts from people who have had them go for their chickens right in front of people. Yikes!!
