I'd set up a conibear trapline on the farm with sardines as bait at every one of them.
Coyotes around here seem to get ALL the outdoor cats.
They didn't harm the damned cats, just chased them. Poor hounds. Look up harmful effects of feral cats on wildlife and see what you find. A dog may want to be a predator, but usually can't. Cats kill everything they can catch. Hence the "coyotes".
