RE: difference between does and fawns
It's always nice to have deer come in as a group to distinguish the size between them. If you have a lone deer, look at the head. Mature does usually have a longer head. Fawn's heads will be short. And of course if you see little buttons on the head, then it's a young buck. Other than that I don't know what to tell you. I'm sure other people have more ways of telling.
