Pokémon breeding/Games/How to breed/Receiving the Egg

When there are two compatible Pokémon in the Day Care, the game will periodically decide whether the Day-Care Man has found an Egg, with the chances depending on the compatibility of the two Pokémon as detailed in the section above.

If an Egg was produced, the Day-Care Man will move from his default position so that the player can know he has an Egg. The Day-Care Man will hand the player an if he or she replies that they want the Egg and if they have an empty slot in their party. If the player tells the Day-Care Man they do not want the Egg, he will permanently keep it. If the player says they want the Egg but does not have a spare slot, the Day-Care Man will keep it until the player returns, when he will offer it again; otherwise, there is no way to refuse the Egg and receive it later. In Generation VII, the player no longer needs an empty slot in the party.
 * In Generation II, he will appear in the Day Care's yard.
 * In Generation III, he will step out of line with the fence.
 * In, he will face the road instead of facing down.
 * In, he will face left or right instead of down and call the player over the Pokégear.
 * In Generation V, he will call out to the player when they are passing by on the road below.
 * In, however, the Day-Care Man will not call out to the player if the player's party is full, even if he has found an Egg.
 * In Generation VI, he will face the road instead of in towards the Day Care.
 * In Generation VII, the Pokémon Nursery lady will fold her arms, with her right hand under her chin.
