Sometimes a shotgun pellet will only knock out the bird unconscious for a little while. Put the gun's safety back on, put on your blaze orange cap, and walk {don't run} briskly over to the flopping turkey and put your foot on his neck. He will try to spur you, and beat you with his wings at this moment --- so stand clear of his legs and feet. Do not try to grab his legs while he's still flopping, or your arms and hands might get spurred --- which btw --- happened to a hunter several years ago; here in Maryland.
