No problem with killing does or Buttons for that matter,they all eat the same to me. I manage the herd with what I hunt with not much strategy to that.
The buttons won't be there in a year or so anyway and unless you manage a big ,big chunk of land it won't help you buck population.
Mom will run him off as soon as he gets in hard horn next year. That's why you see so many
young bucks wandering around like that don't know where they are in Nov. Cause they don't.
Congrats on and nice old doe,I also believe that they are really tough to kill with the equipment we use. No mistakes with them or you are had.
