I think it is just not very old and can just barely walk and can't keep his legs very straight. Most time I get fawn pics the mothers hide them at first and come to the mineral by themselves for a few days before they bring the fawns with .This one must have been born right close by.
Cool pics. I actually just saw my first fawn of the year trying to run with mama for shelter from the rain. I tried to get a pic of it, but it was raining too hard.
