Well Chuck, I left the house at 4:15 this morning intending to give your advice a try.
That big old bird gobbled once on the roost, and true to form, he didn't make another sound once his feet hit the ground.
He did have a buddy with him today, and his buddy would gobble back at my calling once in a while.
I had them, and a hen, just over a rise in front of me for about three hours this morning.
I couldn't see them most of the time, and each time I'd kick back to take a snooze, the younger bird would gobble, and snap me back to reality. It must have happened five or six times.
I may shoot that younger bird out of spite some morning, if I get the chance. It's pretty inconsiderate to yell at a guy every time he starts to fall asleep. :D
Bob
