I put a feeder out once in a spot I had just been dumping the corn on the ground. Had bucks coming to the pile on a regular basis at night. After the feeder was up and running never had a single buck come back to it for the month the feeder was there. Took the feeder out and they came back...
Same here. I've never had a pic of a good buck at our feeder and it was in the same place as last year where I got tons of good bucks on film when feeding of the ground. All of a sudden this year they disappeared. The only new variable was the feeder.
In another location we ground fed and that is where we were getting the good bucks. I think a feeder makes a mature buck a little weary.
