We only feed them in the winter.They just stop coming to the fed on their own.Had 17 come up to the house the other day.The deer was here long before I built a house here.They always had a beaten path in the winter time a couple 100 feet behind the woods.They like the acorns up and down the driveway and right behind the house. I know they would get by without my help,but we enjoy watching them come up to eat.It's interesting to watch the differant ones come out.Most don't stay much longer than ½ hour.Than that group moves on and a few minutes later another group will come up.They always have to pick on the rut and try to drive them away.No wonder they are small the bigger ones won't leave them alone.
