Y'know, although many of the dogs are really thin, I only once saw one menace chickens. I wonder if it might be because these are tough, capable birds and I imagine puppies learn to steer clear of them (plus, there are people around all the time). That one time, I heard the sound of half-grown chicks freaking out, and came around the corner to see a woman shooing them into her fenced yard while holding a feral dog at bay. The dog was posturing and snarling at her from about 10 feet away, and she was scolding the dog, and while this was going on another woman came walking down the road and just kept walking right past behind the dog as if it was all no big deal.
