I have shot a fawn before, accidentally. I shot the bigger of the 2, but it must have just been the female fawn instead of the Mom. I felt bad, but as long as it is going to be used for food I don't believe it is unethical. My son will be hunting for the 1st time ever this season and I will not discourage him from shooting any deer he sees. Ethics are something each person must define for him/her self. Although their are some basic ethics everyone should follow.
