I have been noticing this fawn recently and have observed how its body is wasting away. Although not readily apparent in the first photograph this shot of it walking away shows it protruding pelvis well.
At no time have I observed it with an adult female. I would expect that from whatever cause that it was orphaned and has had to face the winter alone without the guidance and experience that an older deer could provide.
With the exception of a few individuals the whitetail herd in our area appears to be wintering well.
