FC mate and I were apparently thinking the same thing: "Hey, lets feed the chocobos".

Seems that a few of them got fed/trained in rapid succession.



When I opened the window, the only two available to train were my own, and his.

I trained mine(Wynter) and then his(Wyrblwynd).

He proceeded to train them again 5 minutes later.

Possibly reproduceable.

Have someone feed a bird and leave the window open. Open the window and feed any that they haven't fed, and then have them see if they can feed the ones you did. The window did not update to say that the birds could not be trained, so there might be a little lapse in there somewhere.
