Recommend you to farm your own vomps using gardening. Wildgrass from mog in your mog garden, earth crystal, line up the pots and hone your green thumb!
Yeah, I decided that is the route I am going to end up taking. I made 8 mules with 8 pots each. Trying to fill them with arcane and wooden, but settling for Ceramic for now. Still looking for someone selling breeding cards so I have a higher chance of starting with cantor or gallop.
The feed is easy to come by once you can start doing chocobo free races. Check with the person you find breeding cards from and see if they have some chocobucks to spare. Maybe they can get you teh cards and the feed in one stop!
You don't have to be too rigid with the feeding since you can use chocobucks to raise stats later on too. Best of luck with your new chocobo farm!
