I used to pass up a lot of animals and birds over the course of the season, because they weren't what I wanted.
I always liked to shoot a bigger buck whitetail, or turkey, for example, than a small one, and I'd hold out for the big, older does, just for the additional meat they offered.
I'd still rather shoot a mature buck, but because of a lot of wear and tear on my body over the years, I don't hunt as seriously as I used to, and don't pass up as many deer these days.
As far as shooting the biggest does, it dawned on me at one point, that these are the deer that are having two, sometimes three fawns a year, compared to the younger does that usually only have one. It just seems like a good idea to let them live. It's just my opinion, but I think fawns with an old, smart momma, have a better chance for survival too.
I always thought that the biggest bucks bred most of the does. From what I've read over the past few years, the current thinking is that most of the does in my area are bred by lesser bucks.
Even if the biggest buck in the area breeds most of the does, after five or six years, he's past on his genes to a lot of deer. And with all the hunting pressure, the road hunters, and the night hunters we have here, the few bucks that do make it to that age are living on borrowed time.
The older I get, the more conservation minded I become, but I'll be honest and say that I've never given the older bucks a pass, for the benefit of the herd. Not that I've killed a lot of them, but I've killed a few, and hunted some others hard over the years.
I've always loved to hunt, and loved the animals I hunt. I look at a yearling spike horn and see a beautiful buck, and a yearling doe, a beautiful doe.
The bottom line in my opinion, shoot what you're happy with, within the confines of the law, and it probably doesn't make much difference in the long run.
Personally, I think the people that are shooting over their limit every year, and the night hunters, are doing way more harm to our game animals and birds than the rest of us are, regardless of what we decide to shoot, as long as It's done legally. It's a big problem here where I live, and it seems to get worse every year. JMHO.
