Actually, I don't even do this. When I feed the FF down to 1 serving left (a couple of cups) I add water and stir. The I add the whole amount of grain to make up my 5 gallon bucket and stir. It's ready the next morning. I do this about once every 5 days. It sure cuts down on the amount of water I have to keep adding to the coop.Actually you might find that it is quite easy. I have a 2.5 gallon bucket that I ferment a mixed blend feed in. Each day I scoop out what I'm feeding them & pour back in dry feed to start fermenting, add more water and give it a good stir, then seal the lid back on. I keep my dry mixed feed next to the bucket because basically I am lazy & don't wanna have to walk all over gathering this & that
