Day care Pokémon 1:
Female Scraggy with Shed Skin, holding a Destiny Knot (because it has full IVs)
Day care Pokémon 2:
Male Scraggy with Intimidate (hidden ability), holding an Everstone (to pass on it's careful nature).
The guy outside says: "They really seem to like hanging out!"
I get eggs from them, but their offspring ALL have Shed Skin! None of them have had Intimidate, or even Moxie (not that I want them to have Moxie anyway.)
So how come I don't get ANY hidden ability ones, and they ALL have Shed Skin?
