Can you give me the remedial course in fermenting?
Step one: Take feed out of bag
Step 2: Place into fermenting container of some sort (5 gallon bucket ok to make 5 gal of feed at once?)
Step 3: Add water and loose fitting lid?
Step 4: Wait 3 Days ?
Step 5: Drain off water and put into feeder?
Is fermented food ok to leave out for a long time, or does it go bad if they don't eat it all in one day? Because I have one of those 5 gallon no spill feeders, and that's supposed to last them around a week. And do you need to clean out out the feeder pretty often? I imagine there's a lot higher chance for bacterial/fungal growth feeding wet food than dry food.
Weeeell, not quite that simple!
Did you see the trough in my post? That is how I feed my fermented mix. It will not feed in any type of gravity feeder as it will stick and make an awful mess.
I do not employ the "back slop" method of fermenting. I put as much feed as my flock will eat in one day into a single container (the old coffee container I show in the post I linked - you'll have to click to view all those attachments, that will help you understand MY method.)
I add plain clean well water to the dry feed until it is about 2 inches over the grain mix. You do not want to use chlorinated water. If you have city water, you can dechlorinate it by leaving it out on the counter for a day. Mix the first batch well then cover it. I just stab a bunch of slits in the top of the coffee can lid then snap it on.
When you are first starting to ferment feed, you will make a second batch in another container on day two and mix the first batch and add water if it needs it. The fermented feed soaks up a lot of water. Keep the batches covered.
On day three you mix up yet another batch and mix and add water to the first two batches.
On day four, you drain the very first batch you made, which should be nice a bubbly and maybe have a little yeast film on the top, into a fourth container. I just leave the draining container inverted over a strainer in the sink while I go about my morning chores.
Once it drains off, keep the liquid to start your next batch, add more water, mix it along with the other two cans you have fermenting and put it at the end of your rotation. You just keep pulling off the oldest fermenting can each morning to feed from.
If your drained mix is still too soupy, toss a handful of your dry feed into it to stiffen it up a bit then spread it into your feeder. I recommend a trough or something similar to what I have. You can google "feeders for fermented chicken feed" for more ideas.
You'll have to play around with your starting volumes so you have enough feed to last the day. If you run out, give them some dry feed. If you have extra, no biggie. Feed it the next day.
I scrape out my feeder out twice a week and wash it out once a week in the warmer months.
