Thank you all for your support! I only named 4 of my flock and three of those were lost today. I still find it cruel that something killed my chickens and didn't even think to eat it. It would still hurt if they were eaten, but at least I would have understood. I live far enough into the country that no one would notice a missing hawk. My father always told me it wasn't illegal unless you got caught so try hard not to get caught. I have since watched this hawk and must say there is something off about it. Today it has killed three stray cats, my birds, and tried to attack a med stray dog. It has also been what looks like hopping around on the ground quite a bit. Not a single bite from any carcass, just a snapped neck and moved on to the next. It never came back for its kill. When I put all my birds up in the old meat tractor and it killed everything else it could find, it just moved on. If I see it again it won't be visiting anyone anymore.
That definitely sounds very off.... It would probably be best if it vanished.
