I mix whatever grains and seeds i have or can get locally .
My mix right now is 1/2 part austrian peas , 2 parts wheat , 1 part whole shell corn , 1 part BOSS , 1 part whole oats , 1 part safflower seeds , 1 part sunflower hearts , one or two handfuls of shelled peanuts and also use 1 part pro plan select salmon .
On some days i switch feed from my grain-seed-salmon Mix to a wet Mix of Harrel Milling Company's chick start&grow to all chickens .
I'm very lucky to have a local feed mill that makes feeds the old fashion way with meat & fish proteins & fats , and with ground whole grains and etc .
It's amazing how healthy , robust and productive they remain year after year after year with no problems ....... i worm my birds at times , provide them with ground oyster shells and granite grit Free Choice at all times ........ plus cool water in a good shady location .
