If I recall correctly, you also couldn't even queue for a duty if you had your chocobo out. Couldn't cast Protect on it either. So, don't get your hopes up that chocobo will ever see the inside of a dungeon. But also, I'm pretty sure they don't intend for you to be running dungeons solo. It can't even join you in story instances.
