Keeping this in consideration, can you hatch a shiny magikarp in Pokemon sword and shield?
If you get a shiny (eg on the 17th egg out of 30) then you soft reset, place the pokemon that you want to get a shiny of into the daycare (do not touch the ditto) and then hatch the number of eggs that the shiny magikarp was on (in this case 17).
Subsequently, question is, how many eggs does it take to hatch a shiny? Each egg has equal chance of being shiny. Harvest the eggs, hatch, then if no shiny start over. When I Masuda a shiny I get 120-150 eggs at once and hatch them all on one day with tv on or something.
Similarly, you may ask, can you hatch a magikarp?
You need a staggering 400 Candies to evolve a Magikarp but that is because it turns into the beast that is Gyarados. This is the Pokémon illustrated when you first open the app. The baby Pokémon, including Cleffa, Magby, Pichu, recently added to the app, can't be caught and instead can only be hatched.
Can you hatch a shiny Pokemon?
You can also hatch Shiny Pokémon from Eggs when breeding two Pokémon at one of the Day Care centres in the Galar region (one can be found on Route 5 and the other is in the Wild Area). Any hatched Pokémon can be Shiny - just like any wild Pokémon can - but there's a way to dramatically increase your chances.
