If you work with them they may come to trust you. It's a lot easier if they are started when their just little fawns though. From what I understand, the trouble people have when raising wild fawns is not getting them so used to humans that they will never leave. When we were kids my aunt took us to a deer park in California that had a lot of Fallow deer. Talk about getting mobbed, those were some really tame deer!
Too cool, have fun with them.
