I'm not sure why the hawks don't simply tear a crow apart in mid-flight, but I am now a believer. My 15 strong flock of black copper Marans were out minding their own business and suddenly my three annoying Guineas started to make a racket. I looked up and about 50 feet above the ground, two very assertive crows/ravens were 'escorting' a chicken hawk away from the neighborhood! Living right by Tinker AFB, I immediately thought of fighter jets scrambling to escort rogue planes away from restricted space. The crows were pretty impressive. That said, so far, haven't lost even one BCMARANS to a predator and I wonder if, from the sky, their coloring makes unwitting raptors confuse them for pesky crows! If so, my Marans have an awesome camouflage!
