Haven't done it recently. Used to help out my friends father-in-law on a dairy farm. They'd peck holes in silage bags , it would rot and be worthless for feed. Couple of decoys out and an owl decoy on the bags. Electronic caller playing owl / crow fight. They're smart birds and wise up quickly. We'd shoot a dozen or so with shotguns until they quit coming in. Then snipe the others with 17s or 223
