I've got one of these living in the woods about 150 metres away. I rarely bothers the chickens.Oops missed this post when I replied.
I have friends who live right on the water in an inlet in CT and you can see the eagles fish from their dining room table. I think those are some kind of sea eagle not the bald eagles. Amazing sight nonetheless.
