I went for many years without even shooting Does after I had many Whitetails to my credit. Many years we were allowed only ONE DEER per YEAR either sex & then you were done. Old School from the 50s was Don't shoot any Does to let you have more Deer to hunt.
Anyway-once the Bonus tags & extra tags started a few years ago-I started shooting Does-Mature OLD ones from what I could tell. I still do not shoot a Doe IF I think it's this years fawn-If it's a yearling, I will shoot her but let a yearling walk. I'm sure any fawn in our area would survive just fine-it is just my personal choice.
