I'm going to disagree with the others, I say all bucks in the pic., along with fawns. The buck to the far left is only about 1.5 years old. He does have quite abit of black down his nose, and is just starting to get the black check patch. He looks larger than the mature buck only because of his body position in the picture. Note that the other young buck also looks larger than the mature buck. Also, the buck on the far left has more horn already than any doe I've every witnessed. Looks to me like he has 3" or so already. Most doe only have an inch or so. I'll attach a pic. of a herd of doe, notice the lack of black on thier nose and the shortness of their horns.
