Oh no! You must've read my post when I did keep my chickens locked up with nothing but FF. Well, they didn't eat it for three days. So I decided I would just let them out. I wasn't going to let them starve to death on my watch. Maybe they wouldn't have but still I wasn't going to force the issue.
They all eat it now, I started my new chicks out on it and they eat it relatively well. I'm still not sure if they eat it any better than they would if it is just wet it down but who knows. There seems to be some advantage to fermenting, and also I think it helps just too wet it down even if it's not fermented. So when I started out my bucket I wasn't worried about waiting until it fermented to feed it to them.
Because of the food I feed, scratch and peck brand, I feel it is vital to wet it down at least because then they get the nutrients from the powder. Otherwise they're not getting it. Which would be a huge waste of a very expensive food.
So anyway, to end my ramblings, I think chickens will eat what they will eat. I've heard they won't starve themselves and I've heard that they will not over eat, I think neither statement is true all the time. My chickens have made liars out of anybody that says chickens like apples, bananas, cat food, pumpkin, squash, and yogurt or scrambled eggs. Mine won't touch yogurt or scrambled eggs. Mine won't touch
