I have to say its not a great ration as in over all nutrition lacking in omega, oils, salt etc I have had commercial organic mix from B&W feeds in Dorest and hi peak in yorkshire. I am a firm believer in kelp. My layers have a good helping of seaweed and proboitics (I have stopped probiotics as they have some raw left over milk now), all veg waste which is organic as they adore all cabbage and all sorts of bits - apples, peelings etc. Even some left over meat from when processing or meat in the back of the freezer. In general my birds are pasture raised so they get grit and other natural minerals however they are indoor now over the winter so they will get the shell.
I use organic as I am a firm believer to know what goes into foods and def has to be GMO free. I looked into making my own feeds but it worked out far too expensive. Many American sites have endless good information on rations (this is layers not finisher) eg
20 lb whole corn,30 lb whole wheat, 5 lb crimped barley, 5 lb whole oats,5 lb black oil sunflower seeds,4 lb millet, 2 lb kamut, 10 lb lentils, 4 lb sesame seeds, 3 lb flax seeds,2.5 lb kelp meal, 2.5 lb crushed crab shell, 2 lb alfalfa pellets, .25 lb livestock salt, 2 lb crushed limestone, I also feed oyster shell free choice and kitchen vegetable and meat scraps.
I pay around £400 per tonne bag incl delivery. I opted not to go for fish meal due to the sourcing and environmental damage it causes. Sunflower seeds are expensive and should only be feed as a supplement as they are 24% protein.
Would you consider the commercial mix direct from the mill - organic?
