Well go to that place just on that peninsula with the Chocobo tracks to the right of the gold saucer if you are facing the crater
Now go here to catch the good or great ones all I remember is these ones are perfect every time
Ok here at this place keep fighting Chocobo Battles until you find one with a Chocobo and Two Spencers(little lizard heads on the ground type thing) then feed the chocobo a Gyshal green and kill the monsters repeat this until you have 4 of them then go back to your stable and put the ones you caught in it.Put a male and a Female in there. then go to the chocobo sage and buy Reagan Greens and feed it to them also get the other ones to 99 of each of he sages greens then go feed half to the male and half to the female of each kind and then go to the Gold Saucer and raise them to rank A or S if you can but A is a must. Then mate these two with a Carob nut (you can steal these off of a red Raptor thing on the fish tail shape to the left of the Chocobo sages or go get it from one on the islands to the southeast of bone village) once they are at rank A or S and you will get a green or blue Chocobo . Then throw away the Chocobo of the same sex as the Green or Blue one and keep the one of opposite sex then go buy some reagan greens only the reagan greens because the other greens affect has been given to your chocobo already so you should have 999 stamina then go feed all the greens to your chocobo and he will greatly increase and obey you. then go raise this new chocobo to rank S (he should be able to make it if you did exactly what I said).Then at rank S go ride him around or go find his treasure that you can get with him.Then go back and mate them with a carob nut and you will get the other coloured chocobo but I suggest you save before doing this Incase it is either the same colour or sex.Now go do the Reagan green thing and raise this one to rank S and mate them with a Carob nut.
Now you should have a black Chocobo who you should put Reagan greens on. Go to the Northern part of the map to the chocobo tracks in the snow and catch a chocobo with either one Jack Rabbit or Two (just catch it if it is with only a Rabbit) and you should get a wonderful one.Now go and get both kinds of greens for the wonderful one and feed it.Now go to the Gold Saucer and Raise both of them to rank S. Now go to the Island on the eastern part of the map and steal a Zeio nut from a Goblin.
Now go back and mate your black and wonderful chocobos and you will get a gold one. Go get Reagan greens and give it to the Gold one for High Stats. Now have fun:D
