the other day found dead chicken in yard by gate and feathers off the back and feathers around and no other damage. these are big chickens.........heavy reds. today came home and found dead chicken in the yard and feathers all around and just back torn somewhat. looked in chickenyard...........freerange..........and piles of red feather and some black where one of the black chickens escaped. the other day did see a red tail hawk in the neighborhood. was debating if some small dog which I don't know how would get into the chicken yard. now have maybe 4 left. did see one that was bedraggled and back torn but could not get her yet. so does this sound like a hawk?
