Well, I have an Anatolian cross who is excellent with them....all of them. Chickens, ducks and geese. He's almost 6 years old and has never, ever harmed any of them. He will also go into the duck & goose shelters and very carefully bring me out eggs (I can no longer lift up the shelters because I'm 5 months pregnant).
He is an awesome dog.
Our Borzoi was also excellent around all of the animals and almost 6 years old when he died...he never, ever killed or hurt anything--and he was sight hound, of all things. Perfectly fine around puppies, kittens, cats, chickens, ducks, geese, baby goats, horses, children....
Our newest dog is a heeler. So far, so good. I don't give him the chance to hurt any chickens (they are locked up) and he's always supervised outside but that's mostly because he's got allergies to nearly everything and won't stay out of the poop pile.
On the other hand, when one of our neighbor's dogs came over (a German Shorthair Pointer) while I was in town, she killed my entire flock. This was a few years back. Not one was eaten. She actually lined them up. No blood or feather loss, either. I made the mistake of taking Cash (our dog) with us to town and left the chickens out. My mistake.
However, when my parents' chocolate lab came up she killed a chicken and ripped the breast meat off and did eat it. She was a rescue and half starved when I found her so maybe that's why? Again, that was my fault because I had the chickens out.
Regardless, my chickens no longer are allowed out of their runs.
Here are some photos of my dogs...with our other animals...

One of the roosters I let out to bathe before a show....Cash was very concerned that he was out and did not let him out of his sight!
