I only feed free choice this time of year. The majority of deer hit the feeders at night due to the heat. I have some that show an hour or so before dark and a few that show up at first light, but the vast majority are feeding at night at the free choice feeders.
Once velvet is shed around Labor Day, I start the timed feeders up. I do like Mr. T and set the morning for a few minutes before sunrise and have to adjust as the days get shorter. I go ahead and set the afternoon for 5:30 (4:30 when the time changes to standard daylight time in the fall). I don't mind the feed on the ground in the afternoon until dusk/dark in the September. Once it begins to cool down, they'll begin hitting it while it is still light.
