I love this thread, as well as the threads on fermenting feed and the thread on sprouting fodder. This kind of information gets me so excited, and reading other people's experiences with these things is really inspiring to me. Thank you again, BYC community!
On that note, I was researching the topic of preparing one's own poultry feed (not just scratch grains, but the full-nutrition feed), and came across this article:

The opening part of the article is SO SNARKY I'm afraid to read the rest! I am actually upset for the person who drafted such an awesome question, and am finding I will have a hard time trusting the advice of someone who could be so nasty in response. Sigh.
I also found this PDF:

This one seems a lot more straightforward and practical.
Now I'm going to have to research the differences between protein sources. I have issues with soy (GMOs, and I know my own body REALLY doesn't like it), but encountered a vague statement once about the betterness of feeding vegetarian mixed feed to the flock, so will need to research this aspect a bit more.
Does anyone else have some useful resources to share?
Ideally, I would love to be able to produce some of my own poultry feed, or at least some of the ingredients for it, here on my small farm. So I'm busy gathering information. I do NOT want to compromise my flock's nutrition, but would prefer to have them get what they need from local whole Non-GMO foods if possible.
