We fermented our chicken feed when living in the city and they loved it. Also, if you buy a 50# sack of seed, wheatvor whatever is cheapest, and set a few cinder blocks so the holes are vertical... Dump about 1 cup of seeds in each hole, starting a new hole each day. Water maybe twice a day enough to just wet everything, and after you get to about 4-6 days I think, you will sprout maybe 90% of those seeds in a hole. Takebit out and give them the reaulting mat of sprouts and they will almost fight over everyone wants some! Chickens love fresh greens!
