What would be a realistic casuality rate for chickens attacked by raptors? 70%?

    Obviously, these records aren't kept and there are a host of variables (size of hawk, type of hawk, size of chicken, the surroundings where the attack took place, etc.) at work. I'm guessing at least 7 out of 10 fall, due to the lethality of a hawk attack and the disadvantageous anatomy of a chicken.

    The breed of chicken and the presence of a large yet agile rooster will skew the results. Alertness of the breed makes all the difference.

    A flock of CornishX , Freedom Rangers, Silkies, Polish, Houdans will have a near 100% success rate for the raptor. At least in my experience, every one attacked was taken.

    A flock of Orp, or similar LF DP hens may be about 80%. Mediterranean breed hen flocks would be a bit lower.

    A flock of Penedesencas, Old English Games, Minorcas or Cubalayas ranging with a rooster would have near zero losses. I've never lost one to a hawk that had a good rooster with the flock. I get hawks testing them all the time and no losses.

    We've only ever lost 1 bird to a hawk. Was a young pullet. Also had a Barred Rock rooster survive an encounter with a Red Tailed hawk. Those are the only hawk attacks I know of.

    Our worst predator has been the Northern barred owl. They get inside the coop through the chicken door and pick off birds at will. I can't define attacks vs success, but I can say that every time one has gotten inside at least 2 birds have been killed with the owl waiting for more opportunities. In both instances, the rooster got in the middle and defended his hens and the owl was forced to an upper rafter. Once, the owl was noticeably injured by Randy's spurs. Randy is a SLW.

    When outside, our SLWs, BRs, Americaunas and BOs seem quite predator savvy. They stick to overhead cover for the most part which makes them hard targets for hawks but easy prey for an owl.

    My first two chickens were Comet sisters Mouse & Gloria. Mouse was the biggest and managed to lay a dozen eggs before becoming the first casualty. Didn't see what killed her. The next attack Gloria saved herself by jamming between two sections of old fiberglass garage door. The Broad-wing was too big to get in the tight space and only got feathers.
    Before I got outside and it flew up in tree. Then just sat there like, "Hey I'm Protected You Can't Touch Me."
    Next Red Tail had just enough time to bite Mouse's replacement, Goldie's head off before I engaged in 10 minutes of hand to talon combat with it. So in three attacks it was always the Golden Comet they went for. Blue Wheaten Roo, Buffed Laced Polish, Dominique, Wild Game/Americana EE all safe.
    Gave up and spent another $110 to cover entire back yard with 2" net.
