I am a very small farmer and make my living selling eggs from pastured chickens and ducks to a couple of high class restaurants. I can't afford the feed labeled "organic". I feed Kalmbach 20% starter-grower pellets to everybody here, chickens, turkeys, ducks, and geese, and they all thrive on it. It is all vegetarian, but that's not anything unusual, I'm not at all sure that in the US the feed manufacturers are allowed to include anything of animal origin anymore. This goes into the Mad Cow Disease scare, and I think they are forbidden to include the rendering-plant stuff, but I could be wrong. Anyway the protein is from soybean meal.
I personally, this year, observed in Rural King as an employee filled the feeders in a bin full of turkey poults with a very well known high protein crumble manufactured by a very very large agricultural corporation. The poults immediately went to the feeders and started eating, and within 5 minutes by my cellphone clock they all dropped over dead. I've never seen anything like this before. I had in the past occasionally used this product as chick starter; never again! I'll stick to feed from my small feed mill company.
I pay $12.76 for 50 lbs. of Kalmbach 20%, which is manufactured by a family owned company in Sandusky OH, and most of what goes into it is local grown in Ohio, so I feel more confident about the quality. Organic feed at the cheapest store in this area (Rural King) is $40 for 50 lbs. My customers aren't going to pay me more than 3 times the price they currently pay for eggs.
Also, I'm not so impressed with what is "organic". I believe that it's "legal" to fertilize your grain with manure from CAFOs and still sell it as organic. Among other things.
