I have to agree that there is zero waste but do you buy feed and calculate a percentage of it to be wasted. Maybe I'm not saying this right but I don't consider zero waste saving money.Yeah, I think if you go down the rabbit hole of the nitty gritty chemical and biological changes that happen in truly fermented food (I have in the past), there is a small gain in nutritional profile and digestibility of the feed compared to "dry". And then there is the reasonable claim that fermented food is not scattered and wasted as much as dry. So a literal savings in wasted food. All that being said, I am still with you in saying it doesn't actually reduces the cost by any noticeable amount. Would have to be talking some very large scale operation where you were feeding hundreds/thousands of chickens to probably see the "savings" in how many bags of feed you were using, and it would probably only be seen over a long time span.
