thanks again! I think ill try it with just water at.fist and see how it goes. I have well water so all is well there! at first ill just add their feed some flax and some kelp. im curious if fermenting the scratch grains increases the protein? Cuz I got a big bag with corn wheat milo BOSS and something else can't remember and I wanted to increase the nutritional value of it. also I remember reading somewhere that it's not good to feed chicks fermented feed but I can't remember why not... but it sounds like for chicks its extremely beneficial because of the possibilities abd the water. I think I'll give my chickies a good start and ferment for them st least half of their feed. I also already sprout for my chickens but not ferment yet!The jury is out on covering. I place a lid on the bucket. Keep in mind that it grows. I've read that it does need to be covered to aid the anaerobic bacteria and that source said as long as there is water covering it that will suffice. Some people lay a towel across the container. Some use a cooler and close the lid.
Some people just use feed and water, relying on free yeasts in the air as in sourdough bread. The danger is that you'll get the wrong kind.
Some just put a glug of ACV in it for the beneficials that are in the organic mother.
Some use buttermilk for the lactic acid. I think yogurt would work.
Any probiotic should work. I found one specifically formulated for chickens from research done in in Egypt.

It goes a long way, one packet for 28 gallons of water or 400 lbs. of feed. It would probably go even farther in a good FF blend since the bacteria/yeast would continue to populate.
If you are using city water or you chlorinate your well water, you'll need to use a de-chlorinator to keep it from killing the bacteria.
Most cities use chloramine to treat their water and it isn't sufficient to let it stand as the chlorine won't vent off till the chlorine/ammonia bond is broken.
I just use an aquarium de-chlorinator without any fin treatments or other additives. It's usually just called a tap water conditioner and it takes 3 times as much for chloramine as it does for chlorine. Follow instructions, mine is 3 drops per gallon and works instantly.
