Not to bring science and basic deer biology into this discussion, but in almost all cases does drop doe fawns and buck fawns in almost a 50/50 ratio. Mature does pretty much rule the deer herd and they run their yearling buck fawns off onto other properties annually. It's called dispersion. Does dont run the doe fawns off onto other properties so they typically stay on the land on which they are born and assimilate into the established doe groups. To keep the ratio even, just on yearling does and bucks, you've got to be recruiting bucks from surrounding properties at the same rate that your bucks are being run off in order to just stay even. If you've got a property with too many deer on it, bucks will naturally seek out other surrounding properties with better food and cover and your annual buck recruitment will not equal your annual buck dispersion so you're headed downhill before the first trigger is pulled. Look at it this way, assume every doe born on your land stays on or around it. You're going to lose at least half or more of your yearling bucks due to them dispersing onto surrounding properties. Bucks will also leave for other properties if the competition is to high. Mature bucks do not generally like the company of other mature bucks. It's why you rarely see a herd or batchelor group of seven or eight mature, 5 year old or older bucks running together. Example: You walk into a bar and there are 20 hot chicks and 100 guys, you look across the street and there are 20 hot chicks and just 5 guys, where are you going want to get your beer and hang out? That said, bucks are only interested in does for basically 10-15% of the year. The other 10 months, they have no use for them and will not seek them out. If they can live on another property with better food and less mouths to feed a mile or two away, they wil do it. When it comes time to chase tail, they will show up where all the girls live but the rest of the year, you wont see them because they are not living on your propety.

Now let's throw in the mortality differences between bucks and does. Bucks natural mortality is probably 2-3 times as high, if not higher, than doe mortality due to the stress, travel and rigors of the rut, before we even discuss everyone wanting to kill something with horns. Does stay home. bucks travel long distances, cross roads, run themselves down to the point of near death in some cases during the rut. Higher chance of being hit by cars due to longer travel distances, higher chance of being injured or killed fighting other bucks, higher chance of getting hung up jumping fences, higher chance of developing a brain abscess from fighting, a damaged pedicle, borken or shed antler, more chance of breaking a leg, greater chance of being caught and killed by coyotes due to being weak or injured, greater chance to succombing to disease due to being in a run down condition from the rut, proven fact that bucks seem to be more likely to be affected by EHD, we can go on and on. Lot more ways for a buck to die than a doe, other than just a bullet. 100% fact. Not saying that bullets dont kill bucks and they definitley can produce a skewed sex ratio in herd but it's 100% fact that deer harvest is not the only way you can get way more does than your land can support.
