The thought of growing grain fodder (thanks for mentioning, R Scott) pointed me to
Fukuoka.
I hadn't considered growing grain before, but Mr. Fukuoka was growing rice , barley and rye on 1 and a quarter acres. He was getting around 1,100 pounds of rice alone. I'm not sure about barley/rye harvest.
I expect to provide feed for a total of 180 days (this will get shorter as I improve my pastures).
I think a total of 1,800 pounds grain (rice, barley, rye whatever) could cut my feed bill by as much as a third.
Thanks for reminding me about sprouting the grain. I did this with Milo (sorghum) until my supply dried up. The
chickens and the pigs like it. (the geese don't)
John, thanks for the tip about pumpkins for sale.
