Not all animals will reject their babies if touched by a human,
actually, most of the time, it's a false belief. As a children, I've
been told multiples times that this was true for birds, but it is
absolutely not the case, in fact, birds have a poorly developed sense of
smell. As you said, bears have been knows to reject theirs, but again,
this is not 100% likely to happen, and it won't happen just because a
human touched the baby, but most likely because of a bad previous
experience the bear will assimilate the human smell with. (But again,
there's no rule.)
But since we're talking about a fawn here, it is actually a good thing
to touch it to figure out if it's being taken care of or not. I could
use caps lock to convince the audience I'm right, like you did, but
instead I'm just gonna give you a source:
http://www.fawncare.com/
"If the doe is still caring for the fawn, she will lick the human scent
off at the next feeding. Touching the fawn will signal her that it must
be moved to keep it safe. Without human scent the doe may not realize
the fawn's hiding place has been discovered. This is the quickest way to
determine if the fawn is being cared for because the doe will move it
far enough away that you will be unable to find it again."
Oh and since you like giving advises, I don't advise affirming stuffs when you have no idea what you're talking about again.
