OK this is a weird question but here I go. I have a freind who's husband works at a dairy. She ran out of her all-purpose poultry feed. Her husband brought over a truckload of cow/calf feed. He said "it's more or less the same". Well there's no feed tag and he does not know what is in it. Needless to say my freind is upset. Should she be worried as well? The feed looks like grits (you can tell I am from the South). She also free-ranges and provides scraps. Will this feed hurt her chickens?
