They always had a high drop rate, but were non-stackable before chocobo raising was added, which made them a pain to farm.

Work care plans - packages, messages etc. - do have a significant impact on affection, which needs to be counterbalanced by personal care, or not using them too much (preferably both). The rest care plan is unnecessary as long as you are feeding the chocobo regularly, I think it's more intended for those "I'm going to be out of town for a week" situations. When you can't show up and feed your chocobo all the time, alternating between more strenuous care plans and rest would keep the chocobo from becoming exhausted.

All this is useful for *raising* a speedy chocobo, but I was kind of expecting the title to be about *breeding*... unfortunately it's probably too early to say anything much about chocobo genetics yet. (Is it known yet whether or not two black/blue parents will definitely produce a black/blue chick?)
