RE: solitary buck fawns
Sven is pretty much correct. Does will live in a matriarchal group consisting of a "boss" or dominant doe, her fawns of that year, her yearling doe offspring. The male fawn will either be pushed off or just disperse as the doe comes into estrous. It's a natural act in nature to overt in breeding. The dispersal is more prevalant in yearling bucks as they seek thier own homeranges away from the parent doe family group. Usually the male fawns may stay with the doe until the following birthing season when the doe will push off the male offspring.
Like Sven offers, many are orphaned so to speak but are more than adequate for survival.
