If you as a farmer aren't going to take care of them, who is. I dont mind a little deer damage.

Nobody minds a little deer damage but we mind when its typically over 10% of planted acres.

Get a good rifle and a block permit and kill them all if you don't like them.

You'll never kill them all now with a gun and conventional hunting methods.  Just.  Not.  Possible.

I, my two neighbors and my dad could kill a100 in a week.

You're delusional.  If you could kill that many then you don't have a "little" damage.  I like hunting them too but replanting 150-200 acres of 1200-1300 acres of beans isn't ideal in our world.
