We have the same thing at our Grange. The pretty little bags with the cut pic of a chicken on the shelves are 5lbs and about 5-6 dollars, I think. OR, you can get the huge brown sack from the warehouse, no cute pic of a hen on the side and those annoying string closures, fifty pounds for I'm thinking 13 dollars. It's not like the stuff goes bad, so I've got a huge sack sitting in the hay barn.
