A learning lesson: The Op did a great photo shot of the teeth. Notice that tooth 4 is not worn (the inside high point) and has more enamel than dentine, and the back half of tooth 6 is not flat and has very little wear. I'm surprise that folks round off the age of the deer to an even number, they are not Christmas born deer. Nobody got the age correct.....
I think everyone on this site or at least most know what months deer are born in Alabama. When someone states a deer is 2 or 3 or 4 years old it is understood that it is 2 1/2 or 3 1/2 or 4 1/2.
