I know several organic feed mills in PA that also do not use fish meal because of the organic question. Fish meal with Naturox (?) sold by Fertrell is certified organic, I believe, but the hard core organic people may choose not to use it. I buy a local no-soy feed that is transitional organic and has fish meal which I prefer. You are right that one can never be sure, but I feel the farmer is being as truthful as he can and the feed is great. My chickens do better on this feed than any other I have tried. I do like Nature's Best Organic, but I feel that animal protein is needed, as my chickens don't free range. I would definitely buy a Non GMO feed if I could get it. I have to pay $31 for 80 pounds of my feed, but it lasts my 12 chickens 5-6 weeks. It's hard to know who to believe and we have to make our own choices. Good discussion either way.
