No. One dog is bred to be a working farm dog. She is one half Black Mouth Cur. One fourth boarder collie, and one fourth McNab. She is the brains. The other is an American Bulldog. The muscle. My place is only two and a half fenced acres.
My boarder collie type dog is a trained chicken dog. We trained her from puppyhood. The American Bulldog I got when she was 7 years old (she is 9 now). She has never shown an interest in chickens other than their food and poop. She does love to hunt varments, though. So, unless you are prepared to spend a lot of time training dogs (which is the best way to go), you would probably be better off trying to find an older dog who doesn't bother stock to begin with., and one dog is better than no dogs..or one dog and a donkey or lama. Oh and both donkeys and lamas are herd animals, and as such, won't be very happy without a buddy.. my sister in law has two Great Perinese dogs and has no problems with coyotes at all. Before that they were losing turkeys a lot. Haven't lost any since they got the dogs.
