Seriously though, get some stakes in the ground placed randomly throughout your plots and get your hands on some of the old aluminum pie tins, even the small ones from pot pies. punch a hole in the pie tin and tie them to the stake with some sturdy string. Let them blow around in the wind and flash in the sunlight, turkeys do not like the movement, or the noise they make clanging off the metal stake, nor the random flashing of the reflection from the aluminum. It isn't foolproof, but it is cheap and pretty effective until they get used to them, and then you can pull up the stakes and move them around the plot area to confuse them further. This also works with a couple scarecrow men with the pans hanging from the cross arms of the scarecrow.
