Pokémon Eggs

At the Pokémon Day Care you trade a Pokémon you don't use for an egg of the same rarity, walk with it on your Pokébar and see what hatches. One Pokémon goes in, one egg comes out: it is the way to turn the duplicates in your box into something new.

The Day Care

Talk to Edna at the Pokémon Day Care on Route 5 and choose to trade a Pokémon for an egg. Any Pokémon of yours counts: Pokébar, bag or PC box.

Edna shows all your Pokémon, filtered by rarity

There is no way back

The Pokémon stays with Edna for good.

Besides the Pokémon, each egg costs:

PokéDollars;
wild materials of the same rarity, any mix (type materials don't count);
Sigils of one of the Pokémon's types, any mix. They come from Expeditions.

The Day Care trade: what you give and the egg you get

Egg	Steps	Fee	Materials	Sigils
Common Kanto Egg	5,000	₽200	20	1
Uncommon Kanto Egg	10,000	₽500	20	1
Rare Kanto Egg	20,000	₽1,200	12	2
Epic Kanto Egg	35,000	₽6,000	20	2
Extraordinary Kanto Egg	50,000	₽10,000	8	3

Edna refuses a Pokémon that is:

protected, out of its ball, ridden, on the market or on an expedition;
holding an item or wearing addons, an aura or colors;
the last Pokémon you carry (an egg can't fight; the last one in your PC may go).

Hatching

Hover the egg: its steps and everything it can hatch

The egg takes the Pokémon's place on the Pokébar, or a free slot, or the bag when there is none.

Steps only count with the egg on the Pokébar. Hover it to see how many are left.
Taking the egg off the Pokébar, or putting it on, resets its steps. That includes sending it to the PC, trading and selling it.
Teleports and stairs don't count as steps.
An egg takes a team slot: with five Pokémon and an egg, the next catch goes to your PC.

When it is ready, the game tells you and the egg wobbles on the Pokébar. Click it and confirm (outside a battle).

What can hatch

Only Kanto Pokémon of the egg's rarity, as often as they appear in the wild: the rarer in the world, the rarer in the egg.
Ditto never hatches, and there is no Legendary egg.
A Pokémon that doesn't evolve from another hatches at level 1. An evolved form hatches at the level its line evolves into it.
The Pokémon is registered in the Pokédex (with the first-registration experience), but it does not count as a catch.
Its sheet says who hatched it and when.

Everything that can hatch is listed on the egg's tooltip and in Edna's dialog. The same odds:
