If you think about it, this is just one more variation on the same theme. We hear the same story over and over again on BYC, though the legal consequences are rarely come about as they are here.
Many folks believe a dog has more value than a chicken, therefore, no matter if the dog owner was completely in the wrong, the dog gets a free pass, because, well, it's only a chicken, right? We eat chickens; we don't eat dogs in the U.S.
Some of us are fortunate to know that a chicken can be as loving companion as a dog. They can learn their names, recognize faces, enjoy your company and not just as food giver. When my dog passes, I will not get another because I have certain hens who give me just as much affection and attention as any dog I have ever owned. I have found wonderful pets in my chickens because I opened my heart, mind and eyes to what they can really be. To other people, they're only a future dinner. That is why the attitude you see in these stories, IMO.
