I am not a fan of organic feed. Don't find them remotely cost effective, and they are often lacking (or low) in key amino acid profiles. I am much less a fan of taking a feed which was originally intended to provide the minimum necessary nutrition for commercial layers, in commercial conditions, under commercial management (short lifespans before they become dog food etc) below which losses in chickens and egg production exceed feed cost savings, and further reducing their daily intake by the addition of scratch.
HOWEVER.
There are a number of posters here in BYC whose opinions I value who make use of the
Kalmbach Organics line of feeds with good result. and the nutrition (unlike some Organic feeds) is surprisingly good. Most use a wet mash or ferment method as a way to ensure their birds eat the "fines" (the vitamin nutrient powder making it a complete feed) and to discourage birds from selecting favorite whole grains based on flock dominance.
Best of luck to you in your chicken keeping journey.
(I free range too - how much it corrects for inadequacies in the feed is a factor of space, season, and content of the area they range. Its unreliable and uncertain, but can be an effective component of a managed risk approach to chicken keeping. As I said, I do it myself. Flock below, in my sig.)
