PBS recently did a special on the Coyotes. Apparently the ones up north have wolf DNA form Canada (cross breeding), which supposedly makes them very aggressive.
They have taken a few of neighbors sheep, and have tried taking cattle but get ran off by the larger long horns before they can get to a calf. Last night I went out for a smoke, I always bring my shotgun. I turned on the flash light and sure enough I had 3 sets of eyes in the filed from the coyotes. Unfortunately I only had buck in the tube and were out of my range. Tonight when I go outside for my smoke, I will have super X slugs. Despite how much shooting I do, an my range on that same filed they arnt scared, My neighbors sheep are too tempting.
