I have crow hunted with decoys, and without, and have done just as well without. Set up just inside the woods along field edge and start calling. I use natural voice, and hand calls. When you bust a bird, leave it lay. It's the best decoy there is, and the crows go nuts. The more you kill, the more decoys you'll have. You can have a ball! Stay hidden. Many times the birds will keep circlinguntil they see you. Believe me, it can get noisy. The more excited they get, the louder they get----and the more crows will come in. Take plenty of shells. If you're in good crow country---it can get wild in a hurry.
