I'm having problems at the moment with chocobo breeding....

I am trying to get a BLUE FEMALE chocobo... I already have a GREEN MALE one, so need a blue female one to mate, so I can get the black one...

But whenever I mate the blue female's 'potential parents', it keeps giving me a GREEN ONE! Every time!

They are A CLASS. Has this got anything to do with it? I can get a green one, no problem, it's just blue that I can't.

What should I do? Any advice? Or is to keep trying all I can actually do?

It's doing my head in lol
