Wow! 50-60 lb coyotes. We've had them forever but come in around 25-35lbs mostly. They look bigger though. Ours wouldn't take a healthy deer down either. They are heavily hunted usually by groups of hunters out here b/c we have lots of wide open spaces and they run fast/far. I know of one guy who has shot 40 of them just this winter. We never seem to knock the populations down though.
