Of course many chicken feeds have "only" grain in them, but that is much different than organic. The grains in regular are GMO for the most part and have had at least herbicide on them and chemical fertilizer in the ground. Organic is certified to be GMO and chemical free. Now we can argue that with GMO seeds blowing pollen all over the place, that there are no GMO free grains in the good old USA, but that is another story. I fed organic for a while & really liked it, but with animal proteins missing from it, I switched to gamebird feed. In PA we have several organic feeds being produced. The Nature's Best I fed was $25.49 per 50 lbs., so much better than $1 a pound. I think Modesto Milling is in California, so that may be an option for you in Nevada. Have you called around to feed stores in your area to see if anyone carries organic? I didn't even know that the feed store I buy from carried it until about a year ago. Ask around and you may be surprised. Good luck.
