Well your math is off, but I will overlook it this time. I think some are missing an important fact, you dont just switch to a bean only diet. I havent checked the local grocery store for a price check of large bags of beans. I am sure my local feed store doesnt sell them. I still havent researched the beans, but I suspect the beans are just a source of protein. adding some beans to a scratch or layer pellets would raise the protein levels in the feed. Might be something else in the bean that helps too, I dont know. At anyrate, I told the wife to cook up a pot of beans, for me to eat, and I will slip the birds a bowl full.. If it works, I have a mill and I will try mixing some beans in corn and see how well that works out.
