You can Use a chocobo whistle to acquire the action to summon your personal chocobo. Unlike rental chocobos, there is no time limit regulating how long you may remain on chocoback. Remember, however, there are areas, such as highly populated cities and narrow dungeons, that your chocobo will refuse to enter.
The action to summon your chocobo can be set to your hotbar and is located within your Mount Guide found under Character in the main menu.
Chocobo armor, or “barding,” can be equipped via the Companion interface situated in the Character section of the main menu.
