This is a good time to kill coyotes. Of course anytime IMO is a good time to kill coyotes. In a month or so the damn pups hair will be long enough to tangle in barbwire. Shotgun momma when she comes out of the den, and a hammer for the damn pups. Been told this is inhuman on coyotes, so if you feel that way, just let the pups starve. Either way the rancher, and other wildlife win.
