I dont think that there is a such thing as the "BEST chicken feed recipe" if there was then everyone would be using it.
As for the OP's recipe, to me it looks more like a cage house bird recipe than a poultry feed recipe.
I have been playing around with feed mixes for some time and found that one of the better (i wont call it the best) feed mixes contains nothing more than two types of feed.
Chicks 20% protein feed -
39 lbs of 13.5% hog mash/feed,
11 lbs Hubbard Chick - N - Egg
Growing Birds 16% protein feed -
46 lbs of 13.5% hog mash/feed,
4 lbs Hubbard Chick - N - Egg
Laying Feed ,
42.5 lbs of 13.5% hog mash/feed,
7 lbs Hubbard Chick - N - Egg,
.05 lbs Ground lime stone
