This brings us to the next question. Once you guesstimate a doe's age, what do you do with that info? Do you shoot old, young or a combination? Does it matter?
QDM types are fairly uniform on the need to protect yearling bucks, and many of us agree that protecting 2.5 and even 3.5 y.o. bucks is great when you can get away with it. But the question of how to use age when harvesting does is the subject of considerable discussion.
I am of the opinion that this is highly dependant on the herd and the habitat. All the more reason to do your homework and evaluate everything. How about the rest of you?
Good replies, but when I re-read my post, I realize that it was a major hijack. Sorry 'bout that Demoderby4.
I don't want discourage anyone from continuing to respond to the OP.
