I put one of the 300lber's out about 4 weeks ago. Cut off a tree in an area I kept baited all during deer season. I have been out several different times and slung corn around the perimeter several times and stayed out of there the rest of the time. I have yet to have a deer eat from it or even be on the frame in the background eating. At this point I would be satisfied with a pic of a deer looking at it and running away from it. This same group of deer will dang near walk up on a flat eco trailer in the backyard and eat corn off it. What gives.? You guys that are using them, did you have any tricks or time frame it took to get the deer used to them?
