We dont do much in the line of warding off predators, we just shoot them when they come around. Our barns are predator proof for the most part, in the summer when we have meat chickens we keep a radio on in the coop at night, and often during the day when the girls are out in the run. Anything besides a weasel will have a very hard time getting into our coops, so if we see anything coming its "get the gun!!"
