Take any black sock and fill it with pillow fiber.. You can sew the end shut or just take a black plastic tie and close the end.. Throw the now what looks like a black tube sock into the field as extra crow decoys...Surely that sock monster visits your house too.. Take all those now one black socks and make them into crow decoys..I have used them to supplement my crow decoys for years now.. They do work too..They store well too in any sac or bag..
