@jwpeter , there is a FF FAQ article in my signature that you can copy into a search bar. It will tell you all you need to know about the how and why of FF. I have been fermenting feed for my birds for over 5 years now, and they do great with it. Be prepared for your chicks to initially balk at trying something new! When I start chicks on FF, I do so at a very young age. I put a little plop of it on a paper plate, and sprinkle some dry crumble or some scrambled eggs (their favorite treat) on top of it. After a few days of this, I remove the dry feed completely b/c they are converted to the FF.
Aside from the nutritional benefit of FF, there is extra benefit: no waste, and rodents are not able to carry it off, so it cuts down on attracting rodents and wild birds.
