The Purina Flock Block is a great alternative to hen scratch and available at Fleming Farm and Ranch Supply.

The Flock Block is a whole grain enrichment supplement for free-ranging poultry and game birds.  It contains oyster shell and grit, cracked corn, whole wheat, whole barley, whole sunflower seed, molasses and lots more.  The Flock Block encourages natural pecking instincts to help reduce cannibalism.  They come in a 25 lb. block.

Use it when you are going out of town for a few days.  We have customers that cover it with a bucket when they use their normal hen scratch and want to conserve it.
