A lot of the type or style feeder you use depends on habitat and deer numbers. Some areas all that are needed will be a corn feeder if they have good habitat. Other areas it might need a protein feeder if habitat is not that good. Deer numbers/density will need to be known before starting to feed protein. You can use a timered protein feeder also over a free choice. The deer going nocturnal due to a feeder is
. Feeding deer free choice feed will not make them go nocturnal, age and time of year will do that till we get cooler temps or the rut. Deer are not going to feed out in the middle of the afternoon on a 105 degree day in August. They will feed closer to dark and after dark. Also many are thinking that the feeding of free choice protein and seeing deer at nighttime is the result of the feeder. What is more than likely happening is the deer are not living on their land/lease and having to travel great distance to get to the feed. Thus they are there at night only. I have had better deer movement and activity when feeding protein 24/7/365 than any with any other feeder or feed type. It is not cheap but the rewards can be very good if you have the right location and deer.
