What are the requirements for a male to pass down it's hidden ability via breeding?

Question

My female has the nature I want, and I give it everstone (passes down nature) but it doesn't have it's hidden ability, and I am not sure the male can pass down it's hidden ability. What do?

Answer 1

>In Generation VI, any Pokémon, including male and genderless Pokémon, can pass down their Hidden Ability when bred with Ditto. Ditto's Ability is irrelevant to inheritance.

If not bred with Ditto, I think you can't pass down the HA from the male.

Answer 2

The male has to breed with ditto then there's a 20% chance of it being passed down. It also works with the same spicies.
