I'm just curious as to what the supposed benefit is? Apart from a massive increase in price to feed them (I guess that's a plus in some people's mind - "It costs more, thus it must be better!"), the forums on BYC are absolutely littered with people whose birds are suffering dietary imbalance on their very expensive organic feed.
Not because there's a problem with "organic", but because Organic is often also Soy-free (depriving the birds of important amino acids they'll need to get from other sources - aminos not listed on the typical feed label). And/or "whole grain" - which is fine if your birds eat a balanced meal of whole grains (and the very important vitamin powder added to the bag to make it a complete feed for gallus gallus domesticus), but many owners complain that birds select out their favorite grains for themselves, leaving the less tasty bits for those lower in the pecking order, and fostering dietary imbalances.
Wetting the whole grain organic feed and allowing it to sprout, while requiring more effort on your part, will help mitigate some of those concerns, and also help the flock deal with the unusual heat we've been seeing around the nation. If you should go that route.
If your feed is soy free, you want to look for alternate sources of the amino acids soy is high in (but corn, wheat, oats, sunflower, and barley are lacking in) - other legumes like alfalfa meal, fenugreek, or animal sources such asmenhaden fish meal or porcine blood meal (not sure how much organic certified porcine blood meal is available on the market, but I know there's commercial sources of non-GMO porcine blood meal at reasonable price to the larger mills).
Ultimately, its your money, you decidewhat to do with it - just be aware that "organic certified" is not necessarily better, and may actually be worse in some cases. It is more expensive, and different, for good or ill.
