I just wanted to add that I too had a fairly large black snake approach the chicken's roosting area this evening and kill my rooster just after dusk. I walked out to close the door on their hutch and stepped on something in the dark. It was the legs of my dead rooster while the snake was still indeed wrapped around the other end trying desperately to swallow my 12 week old rooster, "Henry." I am so disappointed, as I was waiting each day for him to begin to crow. It was so exciting to see him mature from 1 week, all the way to 12 weeks! I too had no idea that a snake would tackle an adult chicken let alone my rooster! I am sure my chicken hutch is snake proof and if Henry had been all the way in the hutch and I had closed it sooner this wouldn't have happened. Just so sad...
