Hello all. Just a point of some importance. Coyotes are not likely to chase deer. They do not prey on deer. Their most usual largest game is rabbits, but most usual is the common vole, mice, rats,snakes, frogs, ground-nesting birds such as the killdeer, etc. Wolves and coyotes do not share the same ecological niche. Coyotes wil take out Fifi or FooFoo if s/he is chained in the yard, weighs less than about 16 lbs. and the owner is not around. Sometimes coyotes will hunt in a pack of 4 or 5 which has happened near here in suburbs a bit further west of Glenview, IL., where a number of small crossbreeds such as Schnoodles (schnauzer/poodle cross) have been killed.
