We're just south of Modesto and the only thing he knows about quail/gamebird stuff is what he learns from me (which isn't much)...unfortunately his company doesn't carry the feed, he just has customers (feed stores) that carry it...and his territory is along the coast so not local. If you have a local(ish) feed store, ask about Bar-Ale feed, I think they may have an organic/non-GMO turkey grower. Bar-Ale is produced in Williams and they distribute all over California. I feed their all-purpose poultry pellets to my chickens and they do very well on it.
