After a recent visit to a small farm that produces eggs from pastured chickens, and after researching various websites of farms raising pastured chickens, I am finding that all of them supplement with some corn and/or soy, albeit organic. They all chiefly feed their chickens vegetable scraps, worms, bugs, etc. The farm I visited in the central coast area of California follows Joel Salatin's rotational method of the chickens following the cattle.

I have seen the nutritional differences between conventional and pastured eggs in the Mother Earth News article, but wonder if those differences are possible when chickens receive some corn and soy. Perhaps the differences are possible due to conventional chickens eating corn and soy almost exclusively?

Any info on this topic will be very helpful!
Thank you, Mark, or anyone else who can shed light on this topic.
