Its not the face Daryl it the pedicle length and the skull sutures that let you know of a deer`s age.His head suggests that he is no longer a youth!
I have seen other pics of him and he looks a far older animal.
I can only go on what the mate sent me though..oh yes he was virtually toothless as I remember R saying....that suggests he was on the way out yet still fat as buggery anyway.
