Is the the date correct? From that one pic that buck appears to be mature, 5+. Could even be post mature if that pronounced hump on top of his shoulders is not from how he is standing. More pics can tell more about him.
His rump isnít well developed, the hump looks like itís his shoulder blade because of his stance, his brisket doesnít sag, his head isnít too large or rounded. Iíve seen old whitetails with small thin heads, and some more pics would certainly help, but Iím leaning more toward 3.5 in the pic.
