Pepio Nut - 100 gil (Chocobo Farm) Luchille Nut - 200 gil (Chocobo Farm) Saraha Nut - 400 gil (Chocobo Farm) Lasan Nut - 600 gil (Chocobo Farm) Pram Nut - 1500 gil (Chocobo Sage) Porov Nut - 2000 gil (Chocobo Sage) Karob Nut - Steal these from the red dragon creature near Bone Village. Zieo Nut - Steal these from the goblins on Goblin Island.
First off, you should go out and steal a few Karob Nuts and Zieo Nuts. If you haven't rented all six chocobo stables, now is the time to do it. Now capture at least a "Good" male and female chocobo. Once back at the Chocobo Farm, save your game. The results of breeding are random, so its best to save before breeding. If you don't get what you want, you can reset and try again.
Once you have saved, use the Zieo Nut to breed the chocobos. If all goes well then you should have either a blue (river) or green (mountain) chocobo. You should now let the parents rest and go race the newborn for a while untill it gets to at least rank "B".
Once the other chocobo's are rested you should save and then breed them again. This time you need a different colored chocobo of the opposite sex. Example: If you already bred a male blue chocobo, you need a female green chocobo. This might take a while to get the one you want so be patient. Once hatched, race this one to at least rank "B" as well. Now return to the chocobo farm and save again.
Use yet another Zieo Nut to breed the blue and green chocobos. If the results are good, the offspring should be a black (mountain/river) chocobo. You need to race the black chocobo to rank "S". Once that is done, and you have the airship handy, go to the nothern continent. There should be some chocobo tracks in the snow. This is the best place to get a "Wonderful Chocobo". One you have captured one of the opposite sex of the Black Chocobo you have, you need to race it up to rank "S" as well. Your almost done now. You just have to save and breed your Black and Wonderful chocobos together. If all goes well, you'll end up with a Gold Chocobo.
