Just started my flock on fermented food too. Saves allot of $ as they don't need to eat as much, and it's more nutritious. They were hesitant at first, so I gave them little of both dry and fermented in separate containers. Then started to alternate one day dry, next day fermented. I combine scratch and crumble in mine, they really love it now. One thing I noticed if you forget to stir it regularly or have it sit too long it develops mold on top and smells bad, not good for chicks at that point. 2 to 3 days is about right. Making in small batches is best unless you have a big flock.
