Great info. When you go on vacation do they just get regular feed then?I've been fermenting feed for 3 years. I do a simple method of fermenting, it's called back slopping. I only ferment regular feed not whole grain. After getting your initial batch fermented, feed out the days portion, leaving about 1/2 to a cup of the fermented mixture. To that add more feed and water to the consistency that your chickens like. My flock likes a thicker consistency. Leave that sit until the next days feeding, it will swell up, so leave some room in your container for this. If the consistency is not what you want before feeding, just add whats needed before feeding, I have to do this sometimes. If I don't feed them any the next day, I stir it to mix it up. I've never had any mold grow on mine. You might see a white coating on the top, this is not mold, it's yeast, mold will be fuzzy. I've had my current batch going for at least 6 months, with the back slopping method. When I go away for vacation, I put the crock in the refrigerator. This basically stops the fermenting process, because it is to cold. When I get home I take it out and continue as before. I keep the crock on my kitchen counter. A good temperature for fermenting is 70 degrees. Hotter(90) it ferments faster and colder it ferments slower. You do not need to have the feed covered in water, as you will see in the pictures below. This would create a soupy mess that my flock wouldn't touch.
This is before feeding out for the day. You might be able to see a slight white coating, yeast.

This is what is left after feeding out. I add more feed and water to back slop.

This is the consistency that I feed to my flock.
