>>24977060I have quite a few, with notable mentions being a shiny Eevee (got it after several days of off-and-on chaining) and a shiny Furfrou (got it within maybe six or so eggs when trying to breed for a regular one).
Speaking of losing shinies, the only shiny that I encountered before Gen VI was a Blitzle in Black. I found it while training my event Zorua, so I decided to keep it out and weaken it with Fury Swipes considering how weak it was at the time.
