Well myself i wouldn't ponder the situation too long. Hard to understand why they do the things they do, but you can react and addapt to them. You say they are bedded longer and moving out too feed later. I have this problem each year also. Find the main trail from the bedding ------> feeding area and hang a stand further back on it. They should leave their beds before dark and start heading to feed, and you will be there waiting to intercept. If they are coming in and its still to dark then maybe move the stand back another 100-200 yards or so. Good Luck to ya........
