Sounds good and all but I don't wake up early enough to feed them, I wake up around 9 and my chickens are out at around 5am. I've been trying to think of a way to feed fermented 24/7
Your chickens wear watches?

If cutting cost is that important, you'll find a way. Free ranging and feeding FF is about as cheap as it gets on feed costs, so if you can do both you can get by on cheap.
