Wow! I just finished reading this whole thread.
I'd like to add that we really have to keep in mind each person's different circumstances with this sort of thing. Especially that "free ranging" to some means 10 acres of lush grass land, to others 2 acres of grass and woods, and to still others it means 1/4 acre (or less) of fenced in lawn. Those three flocks are not going to have access to the same variety of nutrients from their free range diets.
I have found that during times of least stress (not molting, not having extreme temperatures), my girls can thrive on just what they find free ranging - and with no drop in egg production. Knowing this, i'm not going to have the same nutritional demands from my feed as someone whose chickens are confined to a run or a small yard. If i knew that my chickens ate nothing but what i gave them, i would probably never feed them scratch. As it is, scratch doesn't scare me a bit. It does help to fill out my roosters for butcher, and it helps to balance out all the exercise they get so that they have a meaty body instead of feeling so skinny like they did when they didn't get scratch. If it gets cold this winter, and the bugs and vegetation start disappearing, i will get more strict about my feed.
I would personally love to get my hands on some of this 21% protein scratch someone mentioned, and that's another thing we really need to keep in mind. Scratch does not necessarily equal scratch. If i could find a "whole grain" feed such as a scratch, that had such high protein, i would probably never buy regular feed again.
