Age

Is this just a well fed young deer?

Yes... probably his first set of antlers.

Cold temps make them look much older but I think that is a 2 yr old buck.

2 would be my guess from just that pic.

I can actually see up to 3 on that guy but probably 2-2.5.

2.5

I agree with 2.5…smoke ‘em.

2.5

he is fluffed up some but I do agree that I'd lean to 2.5 from that pic and not 1.5.

Post other pics of him on this thread if you have them
