The broadside buck in first pic, the rest are him also... I know the pics aren't the best for aging, but what y'all think. I think he's just 3.5. I have trouble this time of year unless he's just obviously mature.. No way of telling for sure, but this one is a good one to guess on..
As others have said, this time of year is nearly a guess. However, I don't think that he looks that young for this time of year. I think at least 3.5, and 4.5 wouldn't surprise me once he fills out.
