Pegm- what temperature are you fermenting at and for how long? If kept warm enough fermentation will start at a day if using the "old" liquid in the mix. Both temperature and altitude will affect the amount of time it takes to get optimum fermentation. You might want to try giving your mix an extra day fermenting and see if that has any effect. You should see it bubbling and it may have a grayish film on top. Whole grains take longer to ferment. It is recommended to gradually switch any time you change food, so what you planned is a good idea. I give my feed pretty wet, trying to increase their fluid intake in this cold (-14 last night), but that also results in it freezing rather quickly. Whoever suggested the heated dog bowl, that was a great idea. I already use them for their water, don't know why I didn't think of it for their food. I ferment whole grains and supplements and keep layer or grower dry available for them, I use small feeders (3lb feeders/10 birds) for it and have to fill them about every 5-6 days so they don't eat very much of it. I overfeed and re ferment what isn't eaten.
