Have a marsh that I would like to plant a food plot around/in, with ability to flood. What is the super recipe that ducks can't resist?
I'm pretty sure the feds would take a dim view of THAT!!! (well, of course not as long as you don't hunt there).
If you're going the millet route, then you should use chiwapa millet. It has the largest seed head out of any of the millet hybrids. More food for the birds means you'll hold the birds longer.
