Because of severe drought that has hit our state, quality free ranging probably wouldn't be an option to keep my chickens alive and well for very long. Alfalfa is a good maintenance feed for many types of livestock, it is loaded with Vitamins A, B, E Selenium, Calcium and other good stuff. If is high in protein and calories. It makes for wonderful forage. I free feed 3 strand alfalfa (2 strand can be all stems) along with poultry feed and have done so for years. I keep several bails on hand at all times and should issues arise that I was unable to purchase feed, the Alfalfa could keep them alive and healthy for a very long time. Hay stores for years in the right conditions and a bale can feed a lot of birds for a long time if worked properly .
