Thanks for the answers guys. I would have thought that I'd get a few more replies though.

Two things that I'd add is that I know that the bird saw the decoys, they were about 50 yards from him when he stopped for about 15 minutes. But I'm also sure that he did not see me. Even when he saw the decoys, he didn't seem at all alerted to anything.

What I was originally thinking right after the hunt was that maybe when he saw the decoys and he was expecting something, maybe another call or something. I couldn't do that because I need both hands to work my call, and I already had my gun up. I thought that maybe if I got one of those push type caller that you use one hand for it might have helped.

But what you guys seem to be saying is that when he stopped, he expected the hens (decoys) to actually come to him, mainly because of the time of year. And when they did not move after his long stance, he may have become alerted to trouble. Is that correct? I know that everything that we discuss is not 100%, but I do appreciate your help in trying to understand what may have happened.
