Three dogs, all in house. Large hawk attacks Gold laced Wyandotte hen. Let dogs out. Mastiff (female), charges down hill and chases off the hawk. Mastiff picks up hen. Mastiff eats hen.....the whole thing, feathers and all. Hawk watches from nearby fence post. Lessons learned; Dogs can't protect your flock if they're in the house. Culling roosters has disadvantages. Mastiff loves and protects our flock, but dead/maimed hen = chicken dinner to her.
