Devona, I used to ferment feed for my flock, and probably will again, and like you, I stocked up on ACV, as that was recommended on the thread I was reading. As time went on the point was made that the beneficial cultures were killed by the ACV. So I stopped using that and things went well. I kept the bucket covered with a towel, or some other fabric, and all was well. Until I became complacent and somehow winged insects discovered my bucket, so I discontinued the FF. Perhaps their descendants have forgotten about the magic bucket and I could start again. I also used to sprout for them, an that hasn't happened lately either. Those chickens of the past ate well.
