There's a huge difference between an 'old time' chicken, and a modern laying hen, who will produce 300+ eggs per year! She will do this at the expense of her health and survival, and needs to eat a good balanced ration.
OK, I wonder if this is where the difference lies. Most of my chickens are heritage breeds such as Cuckoo Marans, Speckled Sussex, Buff Orpington, and Partridge Rock; we also have several Rhode Island Reds from a small, local family breeder. I haven't counted, but I doubt that any of our hens are producing 300+ eggs a year. We don't provide supplemental light in the winter and allow our hens to go broody. One of our hens hatched chicks this past spring so she went even longer without laying.
Regardless of the number of eggs they lay, I do believe in the importance of a balanced diet for chickens, so I do feed a good-quality, organic, locally-produced layer/grower feed (switched to grower for the winter based on advice I received elsewhere on this forum) that contains grains, peas, corn, healthy fats from fish oil/flaxseed/sesame oils, and a vitamin/mineral blend. We also supplement protein with dried grubs, tofu, and, occasionally, cooked eggs or meat. And, we supplement fresh produce and dried herbs when pasture is limited or unavailable, as well as provide limited amounts of treats such as oatmeal, cooked noodles, and stale bread.
Looking into the protein content of different types of feed recently, I realized that there is quite a range, which indicates to me that those percentages should be taken as a rough guideline and plus or minus a few percentage points is unlikely to make a life-changing difference. For example, someone in a different thread mentioned that their broiler feed contains 21 or 22% protein, while the broiler feed made by our preferred manufacturer is only 19% protein. Similarly, I believe someone mentioned a grower feed with 18-20% protein while ours is only 17%.
So, in my opinion it's definitely good to make sure your flock is getting appropriate ratios of key nutrients (e.g. 10% protein is obviously too little and 50% is obviously too much) but there is some room for flexibility. Again, this applies to heritage breeds; I have little knowledge of modern production breeds, so it is possible that those chickens do best on a highly regimented diet.
