Stop calling so much. If they are strutting, then they are hoping the hen will come the rest of the way. If you have been aggressive on the call, then the gobbler will assume the hen is hot and will come to him. Thats why he is strutting and gobbling. Usually if they can see the decoy at a distance, and have an open area to strutt, if its just a single hot hen then they will stop and let her come the rest of the way.

I'd nix the decoy and just scratch the leaves. When the bird starts getting closer, quit calling! Put the call down, pick the gun up and scratch the leaves, gobblers cannot resist it.
