Balancing a diet for laying hens is not as easy as it may seem! Originally, chickens are jungle animals in SE Asia, small birds laying maybe thirty eggs each year at most. A decent modern egg laying hen can lay 300 eggs each year or more, a huge metabolic effort on her part! Dual purpose breeds are larger, and still may produce 150 to 250 eggs each year, also a lot of work.
In 'the good old days' on farms, hens might produce 60 to 150 eggs, and have a wide range of food available, including grains fed to other animals on the farm, and many more bugs, worms, and 'stuff' than anyone can have on one acre of 'yard'. Adding lots of vegetable matter lowers the protein level in that diet too, and unbalances it further by changing the mineral balance.
I had poultry science and livestock nutrition classes in college, and learned a lot. Mainly, I learned that formulating complete feeds in HARD to get right, and expensive, and it's all right there at the feed store. Buy organic feed if that's your plan, and don't try to make it yourself.
