How to make chocobo gain levels?

[Kyle]

I can't figure it out. Help. And in detail please.

ok first it's better if you have a bold chocobo cuz they can go just about any where ok you send it out in to the world and goa and do what ever you want to th go back and see what it found and then it should have gained some exp.
not a fulprof plan but it worked for me

My chocobos have not gained exp even when I send them out to different places. The only way I've ever had a chocobo gain a level is by capturing them then seeing Clasko and they have a 10 under the "to next level" thing. So I have two level 2's. I need to know how to level up my chocobos.

Oh, and I have some of every type. Timid, Normal, and Bold.

when you catch a chocobo examine it 2 see what its max lvl is, feed them lots of types of greens to lvl them and send them out to treasure hunt, and keep the heart and spirit up.
