I have water kefir and Kombucha tea going in a continuous brew. I'm thinking of giving some to my chickens. Has anyone here ever tried water kefir for their chickens? I'm also thinking of throwing them my older scobys. Does anyone else do this? With the continuous brew, my Scobys get huge and thick. I've heard of people cutting them up and drying them for dog treats. I wonder if the chickens would like them, too.
