I respectfully disagree. Not EVERY dog will chase and kill your chickens. My last dog spent most of his time mingling with the flock, and actually acted as a flock leader. He broke up fights between the hens, and watched over the younger ones. My chickens were not stressed in the least bit by him. He never, ever killed, chased, or attacked a chicken. Before you tell me that this is an isolated incident, please check out other threads - you will see plenty of them where dogs and chickens can get along. I know, there are also ones where they don't, but I want it to be clear that not every dog will kill your chickens. Especially if the owner has put time and effort into training the dog not to do so.
