I thought it was complicated so I never did it, and someone on the NYDhatch thread made it simple for us!!! FERMENTING FOR DUMMIES or FERMENTING FOR BEGINNERS lol Its funny because I cleaned coops and after I cleaned and saw all that wasted mash and then saw the girls just pushing the mash all out of the feeder I thought I had been so stupid for so long NOT DOING it.... I am going to video tape the girls making the mess and then when they eat the mash FF!! Can you imagine how much time we will save if the amonia in the coop is put off for a longer time period too!! YAY only plusses here!! It may be more work feeding but that beats cleaning any day!!!
