Genderless Shiny Hunts
Forum-Index → Help → Answered → Genderless Shiny HuntsOf course, if you've hatched that pokemon before, it can also be obtained using gems from the gem collector and if you have the chip, from the tall grass (this also depends on if there are any eggs of that pokemon in the tall grass though).
Since your pokemon pair wouldn't have the same dex number though, less eggs would be produced in comparison to a normal hunt.
