If you are talking about moving as the bird comes in or has hung up , it can be done ,,though it too can be risky . You may forget , in the moment of excitement , that if you increase your height at all he just might see you . And , while you are moving he WILL hear your movement and may run toward the hen that he thinks is leaving,,,,and spot you .
But , if the lay of the land allows you to move without being seen , it sometimes works out for the mover . Time among turkeys will teach you and I when to move .
