Tough lessons for some rookies.

Just a question, no suggestions as I'm a chicken newbie: are you absolutely sure it was the dog? Perhaps she had blood on her face from an already dead or injured chicken? And did you ever find the nest of the noisy critters?
I'm so sorry you lost your animals.

Sound consideration. I have to actually see predator in action to say definatively who did it. My dog does not kill chickens but he will bring bodies to front porch, especially those cached by fox working neighbors flock. I have chased wrong predator enough to now avoid jumping to conclusions and loosing more because not targeting correct culprit.
