Egg cycle/Generation V and later

Every time an Egg cycle is completed, the Egg cycle count for all Eggs in the player's party is decreased by 1 (by 2 if a Pokémon with or  is also in the party, but not below 0). An Egg is ready to hatch as soon as its Egg cycle count reaches 0. If multiple Eggs are ready to hatch after an Egg cycle ends, the first Egg in the party will hatch immediately, while the remaining Eggs will hatch&mdash;in order and one at a time&mdash;each time the player takes another step.

Using a Hatching Power (from or O-Powers) will shorten the length of an Egg cycle depending on the strength of the Power used. The number of steps walked in the current Egg cycle is also modified by the appropriate multiplier above. When the Hatching Power wears off, the current number of steps walked in the current Egg cycle is divided by the same multiplier.
 * Weak: 4/5 (205 steps)
 * Medium: 2/3 (171 steps)
 * Strong: 1/2 (129 steps)

In, Secret Pals at the player's Secret Base can decrease an Egg's current Egg cycle count by half of its base Egg cycle count, rounded up. In, the hot springs at Poké Pelago's Isle Avue can decrease an Egg's Egg cycle count over time.
