I never claimed to speak for all farmers. Never even claimed to be a Farmer. I'm just a guy with some chickens. My position is that it's ridiculous to write off killing and relocation as pest/predator management. Deter/repel & kill/relocate aren't mutually exclusive. You lumped them into those catagories. I've had the most success with deter. However, predators are smart and patient. Sooner or later one finds a way in. At that point I opt for kill. The fewer I have to put down the better. If someone else can achieve results with a different mix good for them.
