The only way to control them is to manage there population, The natural predators are not enough but harsh winters can do a number on the herd or over harvesting there habitat, I believe thats whats driving them to more populous areas besides the fact that more people are feeding them throughout the winters now, I'm doing my best to try to cull the herd, But i'm also selective to the size deer as well, Tomorrow morning looks like our coldest of the season upcoming so it will be a rather chilly sit in the woods, At least the winds should be calm.
