That might be a bit over simplified. Nothing to do with the shaming aspect, I agree completely with that. Each place is different, but our place is significantly impacted by immigration. That has an impact on buck-to-doe ratios. Unless you kill mom, most will force young bucks to leave the area as nature's way of keeping the DNA pool from getting too shallow. Without a hole in the social structure, for immigrating young bucks to fill, fewer come in than leave. We have the best summer quality food within about 3 miles. The biologist says that every time we shoot a doe and leave a hole in the social structure, the next summer when native foods get scarce deer from elsewhere start ranging looking for food. When they find our place, if there is a hole in the social structure, they tend to stay and re-home.
It is really hard to have too many bucks per doe. Even with much better habitat than the general area, lesser bucks will tend to leave if numbers get too high. I vaguely recall some study that indicated some change is the sex ratio between fawn being affected by the social structure as well. I'm not sure I've seen a case where a deer manager said they had too many bucks. Perhaps too few does (declining population), but never too many bucks. I presume that could happen in some extreme case but it would be pretty uncommon. If we shoot a few young bucks, we create holes that will be filled by extra incoming young bucks. We tend to save you young bucks for our novice hunters. If we don't shoot those bucks, the number entering and leaving will be about the same.
At our place, the real key is shooting does with button buck fawns. Those button bucks will tend to stay on our place more frequently since they are not pushed to leave. Their odds of survival go way up. Young bucks are most at risk when they are moving through unfamiliar territory. On top of that, we know Mom had great habitat, and that fawn will have had great habitat since birth. Young bucks immigrating in come from Mom's on less favorable habitat and had less favorable habit themselves for the first year or so.
