Head out before light, and set up around 100yds or so (close enough to work him - make him think you roosted there too - but far enough away where you won' t spook him off the roost). Decoys or not to decoys - tough choice, both sides have good arguments, as well as bad. As the sun come up and you hear the birds start to cackle down - give off a cackle call and smack your leg w/your hat (to make it sound like wings) wait a bit, soft clucks, scratch, slowly work yourself up to a yelp (but don' t stay w/the yelp... just enough to let him know you are there)... Worked for me, but everyone has different things that work well for them. Would like to see how others answer as well - constantly learning.
