Actually, this can be true if you have enough forage available on your land to provide most of the chickens' nutritional needs. The birds would also need to free range pretty much all the time as well. I know an old farmer who runs his chickens this way, and we were actually discussing all feed vs. free range with only supplementary feed a bit earlier in the thread.
This something of interest to me as an animal nutritionist. When birds are at low abundance and quality of natural forages is high, I am unable to come up with any formulation that is commercial or custom that can match the natural forages. As the number of birds increases relative to available resources, either the birds must range farther or some nutrients (protein, energy, vitamins, or some minerals) become limiting before other nutrients. During winter, energy becomes limiting first and can be supplied by increased amounts of scratch or sunflower seeds. During early spring when first flush of green growth figures highly in forages available, then protein seems to be limiting since insects have not had a chance to emerge in any numbers and the plant parts consumed seem high only in water and carbohydrates. During summer and fall months, pattern not so clear but some feeds / feedstuffs can compliment natural forages as well as any complete diet, at least for short periods of time. Problem I have noticed is that nutrients of shortest supplier varies considerably over time but the variations may follow annual cycles.
Yes! The problem is knowing exactly when to switch the supplemental feeds to balance the ration. The reality I find is that most "free range" chickens are confined to fairly small pastures, with dubious range. Robert Plamondon is a very successful pastured poultry raiser, and he feeds a complete ration with higher protein, supplementary grains, and calcium year around - and notes that production in his birds although profitable is lower than in confined birds.
Another problem is micronutrient shortages; in the Pacific NW and some portions of the Great Basin, grains are low in selenium.
I know people who are "free ranging" chickens on manicured backyards. Or barren lots. Or feed homemade rations that contain large quantities of high sodium foods such as cottage cheese and zucchini. (As vegetables go, zucchini is high in sodium, as are some Chinese greens.)
My grandparents had yard birds that would squabble over the occasional bot found in horse manure; and tear living mice apart as they went for the good parts. A mouse and yard birds gives a whole new dimension to food running. Chickens were considered part of rodent control as well as keeping insects down.
Old poultry books went into detail on managing poultry ranges; thousand headed kale was a favorite of Professor Dryden.
My background is in human foods and nutrition; but there are definite cross overs.
