I have not lost any chickens to dogs yet, but I do see some strays down in my field once in a while. I'm sure it's only a matter of time before the chickens come across thier path. I love dogs and would have a very hard time shooting one, without giving it some warning. If the worst happens I was thinking about using "rat shot" in my .22 as a non lethal deterant (the first time at least). Thinking the noise and sting combined might work better than pellet or paintball. I've heard the range is woefully short (even when using it on rats) but all I want is for it to sting a little. Anybody used it on dogs?
