Question

In Pokemon X and Y do you earn extra EXP for Audino or Chansey and Blissy?

Why these three?

They give a bit more than the more common pokemon you see.

Answer 1

Audino does.
Chansey and Blissey give normal experience though.

It is a bit more than the usual pokemon you find on routes though.

Answer 2

>EXP yield is a value every species has, and Audino's just happens to be exceptionally high. Nothing complicated, really.

So like Audino's, Chansey's and Blissey's EXP yield is also a bit higher, so yes I believe they do give a more EXP unless Gamefreak changed it, but I didn't find anything saying they did so I assume they didn't.

Hope I helped!
