There is a FAQ re: FF in my signature. You will have to copy the "address" into a search bar. FF is great for ducks, and chickens. I've been doing it for about 6 years. I mix up a 5 gal bucket of FF for my flock. When the bucket is almost empty, I add more feed and water, and it's ready to go the next morning. When my flock is big, I may rotate 2 - 3 buckets, but a single bucket will work for up to 24 adult hens. My preference is to be renewing bucket every 24 - 72 hours, based on ambient temp. If you need it to ferment faster, you can use warm water. Use cold water to slow it down a bit. In hot summer temps, I try to use it within 24 - 48 hours. Make the FF about the consistency of mashed potato, soft serve ice cream, cooked oat meal. Birds don't seem to like it if it is too wet.
