Like I said, im sure you have more pics and better info on him.
I could just as easily see the first pic as being 3.5 as I can the second. I can also see the last pic being 5.5 without much issue. Eye of the beholder and I know better than to claim a deer is exactly an age by on the hoof estimates and especially from just one pic. Im sure wouldn't argue he is older is all im saying I guess.
It's hell eatin em live
