On day number 19 (15 days since it hatched), my chocobo finally hit adolescence. ^^ It has white-tipped feathers, which most likely means that it's going to be a good ol' fashioned yellow one. Here's his info and stats:
Name: Lucky Comet
Age: 19 days
Egg: Bit Warm
Feather Color: White
Affection: Regards as parent
Activity Pattern: Take a walk (3 days), Listen to music (1 day)
Care Pattern: Go on as many short walks as possible
Diet: Gysahl greens, with Vomp carrots thrown in now and then
Available activities: Walk around town, listen to music, rest, exercise alone, exercise in a group, play with children, play with other chocobos, deliver packages, show to public
Available care options: Watch over, take a walk (short), take a walk (regular), compete against others, scold, tell a story
As a note, the option "Compete against others" must be unlocked. I took Lucky on a regular length walk (to Konschtant Highlands), and met three NPCs who were raising a chocobo (with black-tipped feathers, too). Anyway, after comparing chocobos with them, I was able to compete against their chocobo (and Lucky won. Go go Lucky! xD).
I hope this was helpful. Happy chocobo-raising, everyone. ^^
EDIT: Looks like a bunch of other people beat me to the punch on posting this info. >.> Oh well.
