I don't know what BG cd yall got.. But, the one I had from BG said to only call at wingtips and tailfeathers, meaning when the ducks were either flying by or checking out, and NOT TO CALL if they were coming in or circling.. He also made special remarks that Comp calling is NO WHERE near what hunting calling should be.. He said, simple clucks and a quack is all you need.. No feed calling..
