I've known about fermented feed for sometime now, but never was interested in it, until I saw it can save money

So....now I'm interested. I don't know much about it, scrolled through some threads, and found there isn't any articles on it that I could find. So you fermenting experts tell me the basics please? How to ferment correctly, what ratios, and the specific benefits? I assume it saves money because chickens consume less of it or eat all the feed without spilling. Thanks!
