Chocobo Companion levelling speed: Is it fine as it is?

[Dustytome]

How do I use the chocobo stable at a FC house? and how long does the chocobo need to stay there, I need it for leveling.

There should be an interactive sign post on the right side of the stable that lets you stable your chocobo, then you can go through the menu to deal with your chocobo specifically, train it and then immediately take it back out. You can train it once per hour. Note that feeding is for color changing and will not garner any experience for your chocobo (feeding/color changing will require the chocobo to stay in the stables for about 6 hours).
