RE: Homemade Feeder
Multiple feeders will decease the effectiveness. Stick with one or two. Whitetails WILL find them, trust me. You can make a simple demand feeder from a garbage can. Run some allthread thru the can about three inches below the top, to form an "X" to anchor the support cables. Then take a saber saw with a metal cutting blade and cut four slits at 90 degrees to each other just above the bottom of the can, about four inches long. Pound in the metal above the cuts to open them up and form a shelf for the feed. Hang the can about 24 to 30 inches high, using wire cables attached to the "X" you formed. Fill with corn, and then watch the TRAILS to the feeder, not the feeder itself.
Or simply buy a digital, programable timer and attach it to a barrel yourself, or just buy the feeder itself.
