So I have 4 large hens, adults, one pullet, one young rooster. I want to add the pullet to the flock soon and rehome the rooster, I hatched 3 roosters out of 4 eggs lol So I am.reading about fermented feed I have a huge bag of nonmedicated chick starter. I am fermenting some right now, it looks.like mush? I added 1 tablespoon apple cider vinegar, water, feed, and a teaspoon of probiotics. It's in a container fermenting with the lid cracked to let air out. Is this right? And how many days do.you let it ferment? The Chickd starter looks like mush?
