FWIW My :2cents:
Coyotes are cowardly opportunists, beneficial to the eco system and highly adaptable survivors. Its a proven fact that aggressive attempts to terminate them is extremely counterproductive. As noted above, my cattle (who are very protective) pay scant attention to coyotes cautiously scavenging amongst them. Altogether different story when my stock dogs are present and yes they are dog broke and because the dogs are well trained I rely on them to assist me during tagging & weighing. YMMV
IMO Coyotes are a handy scape goat for man's cattle mgt screw ups.
For obvious reasons, sheep are a different deal altogether and in most cases nesesitate 24/7 protection via LGD's etc.
As to who to blame in the death of the calf...you needed to be at the scene but I'd put my money on dog(s). Lost several registered cows, pairs and yrlg replacements a number of years back. All signs (extreme harassment, bodies covered in bite marks, limbs & faces torn off but no sign of feasting)...were clearly the work of dogs.
And yes, the offenders were eventually disposed. Carefully I might add as the offending owner was a major meth and dope producer. :frowns:
