Yes! Yes! Yes!
Chickens, even those with normal beaks, find it much easier to quench their hunger with moist feed. So why not maximize the taste and nutrients while you're at it by fermenting the feed?
It's as easy as mixing water and feed together. Natural wild yeasts floating in the air around us colonize the wet mixture (leave the lid off or slightly askew) and within 48 hours, you have a fermented mixture that is fluffy and much more nutritious than dry feed, complete with natural probiotics, and to my nose, even smells better than dry or just moistened feed.
To jump start the ferment, you can add a splash of ACV and keep it in a warm place (55F to 80F) and you can make it as wet or dry as you want by adding dry feed to it or more water stirring twice a day.
I like mine the consistency of biscuit dough so I mix 12 cups water to 14 cups dry feed. Filtered water will permit the yeasts to colonize more quickly. This feeds a flock of 12 for a couple days at 1/2 cup per chicken per day.
