My family and I live on 30+ acres in Hunterdon County. We frequently have woodchuck and coyote problems (from digging holes under our barn and along our horse trails, to coyotes lurking around the new baby colt). My question is, do I need any special permits to dispose of these pests? I was going to use either my 17 HMR (woodchuck only), .223 (both), or .308 (coyote only). Can anyone shine some light on this for me?
