Just in case this would help anyone who is new to fermenting feed, as I am...
 
I found that it took closer to 4 days to really see the bubbling/fermentation. I am pretty certain it is because my house is pretty cold. I live in a manufactured home and on the 2nd day, I decided to place the bucket halfway over one of the floor heater vents. This got it going!! I keep it there when I am not feeding and it is doing great.
 
Also, I think I am going to switch to the 2-bucket method for sure. I am making a HUGE mess of this stuff every time I feed, trying to scoop it out, drain the water, etc. over 1 bucket. It's a disaster...
 
And lastly, it took me about 1 week of feeding the chickens and ducks to notice a difference in their poo (not as loose and house not as smelly) and also to see a difference in the amount of food they were consuming. At first it seemed like they were eating more food now that it was fermented than they were with the dry!! But now, they are starting to taper off a little. I'll be interested to see if it continues. I also have to keep in mind that it is winter and there's nothing else to eat except for what I give them. I bet in the summer, it'll be great on feed costs!
 
Oh, and even though the chickens took to it right away, the ducks were a little slower. It took them several days to act like they actually liked it. Before that it seemed like they were shaking more of it out all over the place. I ferment a mash and usually leave the ducks' food a little more sloppy than the chickens'.
 
Still learning....
