How can you tell the difference between a male and female baby deer?

You can't tell the difference between a male and female baby deer (fawn) by looking at them. Both male and female fawns look exactly the same.

Here's why:

* No external differences: Unlike some animals, fawns don't have any obvious physical differences in their external genitalia that would allow you to distinguish their sex.

* Developing antlers: Male deer (bucks) will eventually grow antlers, but these don't start developing until they are older.

* Best way to determine sex: The only way to determine the sex of a fawn with certainty is through a physical examination by a wildlife professional.

So, unless you are a trained wildlife expert, it's impossible to tell the difference between a male and female fawn just by looking at it.
