we have 55 gallon drums with a 2 inch hole cut in side for gravity feed on 4 greenfields those fields arent allowed to have does shot on them or anyting less than a 3.5 year old deer we literally see herds in them 4 out of 5 hunts all day long I just enjoy actually seeing them all this the deer go nocturnal talk is BS any deer will go nocturnal if you shoot at them as soon as they step on the field. ive also been experimenting and deer will not touch big and j if there is a pile of apple corn next to it. stuff is a waste of money. theyll also avoid your timed broadcast feeder to come eat at the buffet pile they dont like picking thru leaves and dirt when its piled up 200 yards away.
