Duck question?????
#2
They may come to check out the call if it is by someone who knows how to call. However, when they come, they will be looking for the ducks that made the call, that would be the decoys. So, the odds of them attempting to land or coming into gun range are very minimal. You would be better off with decoys and no call than the other way around.

However, Oldtimr is correct again.. the opposite is true...ducks are more apt to come into decoys with no calls present. As a matter of fact, I've had plenty of instances where greenheads have worked my decoys, come in fast and hard with their landing gear down and I never blew one quack to get em there.
Your chances are much better with decoys present, even if it's just a dozen. If I had to make a choice, I'd rather hunt with decoys and no call, rather than a call and no decoys.
