If you can't get separate ingredients try a bag of 16 or 20% pigeon grain. This has a lot of peas for protein, millet milo & other things depending on the brand. Find Fertrell dealer in your area (look on www.fertrell.com) or something like Fertrell to buy Poultry Nutri-Balancer (Mineral mix), Aragonite or Oyster shell & fish meal if you want animal protein. When I do it, I use 50 lbs. of16% pigeon grain, 50lbs. of wheat and then mix the minerals & fish meal in. This is not a cheap way to feed. 16 % pigeon is $20, wheat 10.50 and the fishmeal & nutribalancer about .80/lb. I will be around $18-20/50 lb. with 18% protein. Contrary to some beliefs, it is not that hard, as long as they get the minerals & calcium they need. Read the labels on the grain mixes you are going to get & go from there. Free ranging should make it even easier. Good luck. You can tell if your chickens are looking healthy & producing or not. JMHO
