Breeding two Pokemon with normal abilities will never result in a Pokemon with a hidden ability.
To breed a Pokemon with a hidden ability, the female Pokemon (or a male/genderless Pokemon being bred with a ditto) must have its hidden ability. It will have a 60% chance of passing on the hidden ability.
This does, unfortunately, mean you'll need to catch or trade for a Pokemon of the right species with the hidden ability to begin with.
Ripped from source because it's put so perfectly.

I tried for Gale Wings Fletchling for goodness knows how long before I realised.
Sorry about that, pal, you're going to have to get one by trade.
Just a heads-up, using the item Ability Capsule does not change its ability to its Hidden Ability.
Huge edit:
As sumwum pointed out, Gooey Goodra is indeed hidden ability Goodra. I overlooked it by mistake. This renders my entire answer null and void, and I sincerely apologise.
Further, that means Chaz17 (i.e., you) are insanely unlucky, because I see nothing wrong with your approach. I am not sure if there can be any other problem, as far as theory is concerned. Keep trying, though, the (flawed) Law of Evening Out suggest you'll get one. Eventually.
On a side note, buying a rabbit's foot or a horseshoe about now would be a good idea. (Just kidding :p )
