*You just need to breed one Good or Great chocobo with any other Chocobo. You must feed it a Carob Nut. The other chocobo's type (good, awful) does not matter. The chocobo's rank is not strictly necessary, though the higher the rank, the higher your chance is of a successful breeding.*Several mistakes here. The other chocobo's type DOES matter. If you breed a good/great with a non good/great there's only a 25% chance that the game will ignore the 2nd parent and try to let you get a blue/green. Also, ranks themselves are entirely irrelevant. The total number of wins between the parents is what matters.

(below chances assume you're using a carob nut)

4+ wins and you have a 50% chance blue and 50% chance green, 0% chance anything else.

3- wins and you have about a 27% chance blue, 27% chance green, and 46% chance yellow.

Again, those 2 sets of odds assume that both parents are good or great (in any combination).

If only one is good/great AND you pick it first, there's a 25% chance that the game will use the above odds anyways, and a 75% chance that you'll just get one of the colors of the parents.
