It's debatable. I don't believe all the hype on it as far as it being superior to just regular ole commercial feed. If there was a huge significance commercial growers would do it.I'm interested in how well fermented feed works? does it cut your feed cost?
I started mine on fermented organic corn-free, soy-free feed from day 1. They go crazy for it every morning - much more so than the dry feed that is free fed all day. They're only 7 weeks old right now, and as babies with a new chicken mama, they wasted a lot of dry feed by throwing it around. But the fermented stuff, they lick the bowl. It's a good way to get them to eat the "fines" (the powdered vitamins in the feed), that stuff that might otherwise be left at the bottom of the feed bag.
