With WHOLE OATS or RE-CLEANED OATS. You can put oats in a bucket (2-5-10-55 gal) and add water until it completely covers the oats. Cover loosely and leave it one day. Next day come back and fill bucket with water again. Cover it loosely and leave overnight. The third day, you can dip the oats out and feed it to your fowl. By then it is starting to ferment and they will LOVE it! Don't worry about it going bad either. It won't go bad even though it smells like it is fermented. Just add more oats to the water and feed again. Once again, this is for WHOLE UN-ROLLED OATS. Sometimes called re-cleaned oats. Jmo
