As of last week the deer still had their horns on their head yet. I had my cameras out and got a picture of a 1 1/2 year old 5 or 6 pointand a mature 8 point with their horns on yet.
So I would say it is a little early yet. By mid Feb. they are usually off their head. By the end of Feb. it is almost a guarentee that they are off.
