I used to kill a mature doe, now I will wait and kill a doe fawn. The reason is they will be the first to go in the winter months. Winter of 2003 I found 39 dead deer 99% were fawns. In 2005 I found 17 and all were fawns. These were two bad winters and it didnt take me long to figure out why I should be shooting doe fawns instead of mature does.
