Don't read if you are squeemish - -
I lost 3 chickens 8 weeks old in one day. My dog is really stupid and will show guilt if I confront him and he showed no guilt when I showed him the birds. He is protective of the flock - but will chase them occasionally. When discovered, the freshest kill had only the eyes missing and the lower jaw. It was a very fresh kill so fresh I considered ( and then didn't ) cleaning and sending it to "Camp Freezer". It became dark and I stopped looking for any other birds. First thing in the AM I went out looking. Found 2 more birds , scaring a hawk off the carcasses. The hawk was eating them in place and returned to finish the job as I left them for the "circle of life" thing. The last 2 were right next to the house with plenty of cover, long grass and they could have hidden under the LP tank if nesc. The partially eaten birds, found with the hawk on them were eaten in this order: Head, body, legs last. There was a circle of feathers at the site of each of the second & third kills. We have those red tailed hawks on our property. They never did take the kill anywhere but ate it on site. So, it could be a hawk too, and not the dog. I agree dogs and canines will kill for sport but don't count out the hawk.
