If they cut the grass there will be green grass growing and the deer will still be eating it. For as far as the rut here the main rut takes place around the 14th. However they will be rutting later in the month. That is exactly why you have early fawns and late fawns. It is not uncommon to see a buck traveling with a doe the week after Thanksgiving here during our black powder season.. But for now I would be watching and waiting near the acorns. After a light rain the deer will bed in the hardwoods early in the day.. Good Luck to you..
