My feelings are that since deer are "heard" animals, the fawns would be ok. They would just be absorbed by the surrounding deer heard.
I get one tag a year I am not even going to consider a doe or a fawn. Now please understand I do not hold or judge anyone by my standards but I just don't consider it sporting, if I wanted or "needed" to shot a doe or fawn I could get the deal done in about 15 minutes.
