Thank you. You just gave me a great idea. I have been dumping the "dust" that collects in the bottom of my feeders because it clogs them up. I guess I can use that dust in my fermented feed.
In some feeds - particularly the whole grain feeds, the "dust" is the most important, nutritious, part - generally a multivitamin, enzyme, amino acid booster like one of the Fertrell's products. Wet mash, as a management method, helps fix a lot of different issues, with a lot of different feeds - from picky birds with whole grain feeds to waste crumble and bottom of bag powder. But nothing's perfect - it ain't so great below freezing (rather time-limited) or in most feeder designs.
Finding a method that works for you, your birds, your situation is part of the process. There is no "one, right, way" - though there seem to be tens of thousands of wrong ways.
