that's a crazy difference in size between them two, if they are from the same mother
MY guess is maybe one of them fawns mother died and this one just is allowing it to follow it about.
not that uncommon, when you think of all the road kills and such?
as them two fawns look like there at least a month or more apart in age/size! even the spots are almost gone on one compared to the other!
that or the other one must have been super tiny when born ??
