That's awesome but sounds way complicated. I just put feed in a tub and fill with water. 2 days later I start feeding. My biggest complication is I get feed from a mill.
I've been fermenting feed for about a year. The chickens like it more. I've seen clickbait that you can save 50% on feed but have only heard people get about 25% savings.
No they will not get drunk as long as you dont add yeast and cook it in a barrel lol.
