Miqobot automates the racing part. You have to do the breeding yourself.
I recommend the ‘Sagolii Road’ track for leveling up your Chocobo because it’s the shortest one. I personally switch my waypoint preset whenever the bot runs into too many obstacles. That’s why I recommend having a preset for every rating category.
For more information on how to breed Chocobos I’d just watch a YT guide.
