We had 6 eight week old hens. 3 Buff Orps, 3 Light Brahmas. Our 4 year old Great Pyrenees dog had been a perfect gentleman around the birds. I had let my guard down and quit worrying about him being in the yard while the birds were loose. Tonight I went out to clean the coop and to get everyone ready for bed when I found the remains of all 6 birds. Most were near the coop. One had made it back into the coop. She was the only one not eaten. I can't believe that this is the same mild mannered dog that has let the chicks crawl all over him during nap times. Dang it.
