That's a hard call to make. It could be several factors. One key thing you could have explained is to say whether they are eating it or not. The feeding sign will reveal this. I'm assuming they are, but under the cover of darkness.

If it is still green there, the deer still have good foliage to eat on or there still is a mast drop and your plots just aren't on the menu yet. Your continued activity around those plots may also be something the deer are using to pattern you.

I don't want to assume, but I find it hard to understand you're not having any luck after that much hunting over those food plots... unless you are seeing does and young bucks, but not any shooters. Or do you mean not seeing any deer at all?

I wish I had the problem of deciding which of my plots, corn or soybean fields to hunt over. That must be hard to make such a decision. LOL!

Good luck,
