Wow ! Im sorry all that happened to your flock and you! I know how you feel all of my birds are personal pets and I love them , I also have alot of dogs that don't chase my birds but they were raised up together, I did have one problem with one of the poodles chasing once but it was sorted out in short order All it took was to make the dog submit to the chickens,Of course that wouldn't work in all cases, my dog was raised with the chicken and it was a case of chasing rather than attacking them but it was still not exceptable and he was taught not to chase them. I don't want to sound like Im sticking up for the dog, but it is just a dog, and the owners are responsible for his actions and should in my opinion be held accountable. I think that the dog should be removed and placed with someone that can train him to not chase lifestock, if that isn't possible then I guess that putting the dog down would be the only option available, though the dog would pay for a crime that his "owners" were totally responsible for. Neglagence in dog owning (No excercise, lack of attention etc....) can lead to many, many bad behaviors in dogs. Again I'm sorry sorry for what happened to your birds. Best wishes, hope you get it all worked out. Sandy
