Some of the best advice I've ever received is how to ferment chicken feed and grains. My chickens looked good and healthy but my bantams seemed skinny. Then it was suggested to me to look up fermenting my food and grains. I googled it and watched the video's. After I started to ferment my feed. What a difference. The chickens walk around with their crops so full and they seen so content. Even the skinny looking bantams look so much better. I still leave the dry feed for them to peck at, but they really go for the fermented feed first thing in the morning.
