I just read this thread and would like the fermented feed recipe, please.
With pleasure. This will feed a dozen chickens.
12 cups filtered water (or let it sit overnight to let the chlorine in the tap water gas off) It ferments quicker.
14 cups of dry feed.
A splash of ACV to get the ferment rolling quicker, but it's not necessary. Yeasts floating in the air will colonize the mixture.
Mix in a plastic container and set somewhere warm between 55F and 80F. Warmer means faster fermentation. Stir twice a day. You'll know it's fermented when you smell a pleasant yeasty odor and the mixture becomes light and fluffy instead of just soggy and wet. It takes about 48 hours for the first batch to ferment. The FF is at its peak of nutrition when it's in this fluffy state. As it ages, it sheds back some of its water and becomes more liquidy and is losing a bit of nutritional wallop. I add a little more dry feed to absorb the excess liquid.
You can add more water to the recipe for thinner wetter FF or more feed for thicker, dryer FF. I and my chickens prefer it at the consistency of biscuit dough. You can add other grains to it, but the chickens will pick them out first when you serve it, be forewarned. If you add too many seeds, they may fill up on those and ignore the rest of the FF.
This will feed a dozen chickens for a few days. When you get down to a third left, use a half cup to start a new batch in another plastic bucket. This will only take 24 hours to ferment if you use filtered water. You can cover to keep out bugs and debris leave the lid with a gap for air circulation. I've never had a mixture mold doing it this way.
A chicken will eat about a half cup of FF per day, large breeds a tad more. Most of us feed once in the morning and again in mid afternoon. Your chickens will let you know.
