Chicken grit and shell dispenser

Offer hens oyster shell and grit free-choice from a wall hopper

Laying hens need oyster shell for strong eggshells and grit to grind their food, each offered separately so they take what they need. This two-sided wall hopper feeds both into a front trough through low ports and holds a week's worth. GRIT and SHELL are raised on the front.
