A spotted fawn in Oct/Nov in my area is as good as dead come winter. The fact that a deer has a fawn or fawns late enough to still be spotted com FALL - tells me there are too many deer and doe especially. Most often - the fawns with a doe come hunting season, are not spotted and are fully capable of fending for themselves.
I'd never let the presence of fawns - spotted or not - influence my decision on taking a doe in hunting season.
