>>16065195 >Should I collect eggs, box them, then go to lumiose city or just ride on route 7 and collect eggs as they appear?
There's no significant advantage over boxing eggs and using the coin trick on lumiose as it will still require you to go back to a pokemon center, press A when an egg hatches, and go back to the center when you hatch everything. The time you spend waiting for eggs to be laid, just to end up boxing them and hatching them later, is also valuable time you could be using to hatch simulataneously. TL;DR: Get eggs as they're laid, box pokemon as they're hatched, stay on route 7. Riding around waiting for eggs to lay is time you could also be using to hatch.
>Is the shiny rate higher in the Friend Safari?
The majority of /vp/ thinks that this is true, but there hasn't been a datamine of the X/Y ROMs so nobody can say what the probability is for sure. It appears to be on par with the Masuda Method's probability of 1/1638. In addition, pokemon found in the safari will always have two maxed out IVs and have a chance at having a hidden ability, unlike chaining (see below). It should be noted that you aren't allowed to use the Pokeradar in the friend safari, so chaining isn't an option there.
>How do I fish for shiny mons?
See the GFShinyGuide link in OP. While far easier to find and catch than with the other methods, the pool of available pokemon attainable from fishing is small, and because they much easier to catch, they aren't valued as high as other non-fishable shiny pokemon. Don't fret, you can usually throw a fishing shiny up on the GTS and get most any non-shiny pokemon for it including legendaries if some poor shmuck who doesn't know their worth falls for it. No hard shiny to normal fish ratios yet, but a rough estimate brings it around 1/200 at maximum probability. It should be noted that the mechanics of shiny fishing aren't entirely understood
