Yeah, in hindsight I probably should have grabbed something larger. It would have sucked if the animals had attacked me directly, or if I ended up having to go inside the coop (close quarters) with just a bolt-action .22LR. I grabbed the Winchester 69 without thinking, it is the gun I always use for critter control, I leave it leaned up against my office door with the 5-rnd mag in my desk drawer. May not be the most powerful piece of hardware, but I can shoot the tail off a mouse with it.
I remember the first time I went rabbit hunting, I asked where should I aim for, my grandpa said "Anywhere in the eye is OK." So that's what I do
Animal control finally came & picked up the carcasses today. 2 birds dead, 2 injured although I'm fairly confident they will both make it. What sucks the most is one of the fatalities was my only Americauna, so no more green eggs
Strangely enough, the animal control officer lives just 2 miles away, she recognized one of the dogs as having gotten into her coop before. She asked if I wanted to cite the owners and press charges, I declined. I don't want them knowing who I am so I'm not harassed later for killing their pets. She said "All they will know is that the animals were caught killing someone's livestock and shot, they won't even know it was chickens.
Thank goodness I live in a farmer-friendly state
Entirely your call and everyone's situation is different... That being said, I'd have told the AC officer to cite them with everything he could think of and let them know a bill for your losses is coming. Most people need to be hit in the wallet before it sinks in that they need to change their ways. This time it may have "only" been chickens but next time it could just as easily have been larger, more expensive livestock.
