This is concerning Pokemon Black.
I have a female Staravia with hidden ability Reckless and I'm trying to breed a Starly with both an egg move Roost and the hidden ability.
So far I've bred ~20 eggs with a male Unfezant and each and every hatched Starly has the standard Keen Eye ability. I've breed 10 eggs with a male Starly with the same results.
That seems unbelievably unlikely considering Bulbapedia's claim that there is a 60% chance to pass down the hidden ability. Am I missing something?
