We find when there is feed available, the deer will come after shooting hours. Food is there, why come out early. That is why we only feed after we are done hunting for the season. 1) lets us see what made it through the season 2) better chance at finding sheds on our property. Our food plots are a different story. Deer are in them a lot, and not just after dark. The previous guys hit the nail on the head, you are the pressure that is keeping the deer out until after dark.
You're correct about the sheds, and This season I went a whole month without feed in the feeder, and nothing happened... I do agree with the fact that the deer do know that food is avaible anytime they want to eat it! That's a given! Thanks for the input!
