Coyotes are very common around here, and never put a dent in the deer or children population. The deer (and turkey) for that matter are much bigger pests with all the car accidents they cause. I know of at least one person killed in a car wreck after hitting a deer on the highway. Every person in our household (of 6) has had at least 1 deer hit on the road and cost us thousands of dollars in damage. The local sheriffs department lost 15 cars to deer collisions in one fall/winter season. We've never lost any chickens or cats to coyotes, but stray dogs are way worse problem out here. When I lived in Oklahoma (land of a zillion coyotes) we lost our entire flock of Barbados sheep to the neighbors loose rottweiler (promptly shot). The foxes and bobcats are pretty common too, but much more shy. Generally this area is so packed with raccoon, possum, ground hog, mice, rats,....the indigenous predators don't need to spend much time on bigger stuff.
