I read about this story on another site a while ago. After some comments with criticism along the same lines, a wildlife rehab specialist* posted and mentioned something about the ears being curled, which meant that the fawn was badly dehydrated. It seems that the “idiot” most likely did the right thing in this case.
* may have been a person from the place where the fawn was brought to be rehabbed?
Anyone who knows wildlife could plainly see the little thing was in dire straits.
The lady saved its life.
