One thing I'd like to add. I just came in from taking our two dogs on their "pee walk". Normally the dogs, an irish wolfhound mix and a border collie, are kept inside the fenced yard. At least once a week or more if it has rained, I take the dogs for a long walk around the area that my chickens frequent. Being dogs they pee on every interesting scent they find. It may help to keep predators at bay, it might not; but it doesn't hurt.
The coyotes have already tangled with my irish wolfhound once. I don't think they're anxious to repeat the experience.
