Well a ten pound Murray McMurray Chick Starter Organic Base will make 210 pounds of complete feed. I suppose you get to pick weather and how much corn or soybeans you wish to add. I understand that this would need to be ground up however, it is not a feed in the bag ready to go, but a base that needs the local supplied corn and or soybeans ground up and then mixed into the starter/base. Looks like you can taylor the protein somewhat with or in the material you need to add.
