lol, i kind of had the same experience too, i was dexnaving for a skarmory and couldn't get one after a chain of 200-300 and the chain broke. so i decided to hatch a ralts with attack, special defence and speed iv's with it's hidden ability and out of nowhere, a shiny popped out after 8 eggs without doing the masuda method. that's just great karma. so don't give up. You can always do the masuda method. it's a win win situation, you get your shiny ralts (only if you do intend to hatch one) and everyone get's a regular lvl 1 from wonder trade :P good luck though :D
