I'm with you Bill -

They are mostly afraid of humans and even Deer from what I've seen. I've watched the feed in the same field together - at the same time- (deer for clover - Coyotes for Mice)

I don't doubt that some wolf lineage may be present - but I think Bergman's Rule applies - and its normal for Eastern Coyotes to be 50-70 lbs 9in the NE.
