I've been feeding fermented feed for over a year. We hand mix our grains so we don't ferment layer feeds. But, you do not want to do the entire bag.
We have a 5 gallon bucket. I usually fill it 3/4 of the way with the grains we feed, add any additional things we add (kelp/nutrients/oregano/etc). Then I fill the bucket with water and give a good stir. If it's just started, I let it sit 2-3 days depending on weather. But mine has been started for a long time, I backslop. Basically that bucket lasts about 2-3 days for me. It does not mold and doesn't stink.
When I get down to the last bit, I leave a little and a bit of the water (mine doesn't have a lot left as it soaks most) and add fresh grain and supplements and water and stir good then use the next morning. I do keep a lid on mine because mice will get into the bucket, I leave ours outside in the carport. I've never had any issues with air exchange as we are in it each morning. Mine also get daily produce/egg shell scraps with it as well.
Ours love it and look great!
