@Grovyle: They always used background ponies as crowd fillers in earlier episodes. In Pinkie Pride, Derpy is shown as a filly when Cheese Sandwich got his cutie mark in that flashback. And Cheese Sandwich is likely around the same age as the mane 6. So that would mean Derpy is around the same age as the mane 6.

Like I said earlier in the comment, before the writers gave attention to the background ponies, they just used them as crowd fillers with no logical explanation. Hell, they've shown multiple versions of the same background pony in the same shot before.
