I ferment off and on. No particular pattern, sometimes I get busy and forget to make it, or I decide it's been a while and change it up. Sometimes I just wet the feed, others I let it ferment a little. I don't ferment for cost savings but for the health of my flock. When I fermented regularly I saved about 1/3 on feed costs.
ETA my chickens have bricks with various coarseness to keep their beaks in order and are not kept in a run.
