It will be a cute little Pidove. All eggs will hatch as the mother Pokémon (or in this case, whichever Pokémon isn't Ditto).
The only time you will hatch a Pokémon that is not the earliest one in the chain, is Pokémon like Snorlax and Mr. Mime who had baby forms introduced in later gens and now require you hold an incense item to breed their earliest forms.
Hope this clears things up. Good luck breeding your Pidove!
