well to be honest its super hard for any real guess on them pic's
you need to see a lot better views of teh face and side view to get a good idea on how its filling in or out
But as a wild guess I will say there either great 2.5 yr olds or 3.5 yrs old but thats justa real wide guess aging deer by looking is all in details and still a guess
with the rut coming on and nexk swelling up it can get harder
nice bucks any ways good luck
