I say the same ...........3 1/2 would be a mature buck. I just didn't see any in your pics.
Hey Greg......I won't make any personal attacks on you (but you did kinda stick a boot in your mouth with this one)......but maybe this will show you just how much you DON'T know. You HAD to know I was smarter than this. See......one of these deer is on my wall....and the other will be...as soon as my taxi's done with him.
They were both jawbone aged.
Here's how I might know a little about the two deer in the last photo (the 3.5 yr olds) I posted. Note one of them is 4.5 yrs old when I'n holding him.....but they were both 3.5 in the last pic
