Last year we lost 13 Jacob four horned sheep, 12 goats, and close to 50 chickens to coyotes & hawks.
DH's Great Pyrenees dog disappeared the year before. (a different story).
We got a new 4 month old GP puppy, and have only lost one Pygmy goat since. I think she was stolen, though. She was very friendly, and the goats got into the horse pasture, which is fenced with barbed wire, and I believe she went to the road on the other side & someone took her. DH thinks a coyote got her.
I have since gotten 2 female GP pups, & my male got killed on the road. (another story). I just got a male GP pup today, 7 weeks old.
My girls do a great job, even though they are only 6 months old.
I haven't lost any of my free range chickens or their chicks from predators since I have gotten the dogs either. I have lost some of my pullets to cats, the dogs can't get next to the runs without a lot of trouble and the cats can climb in & out by way of the trees, so they can stay out of the dogs reach.
Sounds like an ad for Great Pyrenees dogs, huh???
I just love mine, and recommend them for protection of all kinds of livestock.
Sorry for the long story.
