It takes some luck. Make sure they are of the opposite sex, and that the yellow one is a "wonderful chocobo". Just reset the game if you don't get a gold one and try again.
The chocobo I used was actually bred from a yellow and Black Chocobo. I figured since she was faster then her mother that she was automatically Wonderful. Is there anyway to tell if that is what I bred?
I really hate Square Enix for this?
You forget that this isn't just some brutal sport where everyones out to kill each other. Its much more like a game of physical chess.-looney liam
