Add the DuMOR Oyster Shell Calcium Supplement for Chickens to your hens' diet. Calcium is such a crucial nutrient for the development of strong, healthy, unblemished eggs, and that's why it's so important to make sure your egg-laying birds are consuming enough of it in their diet. This chicken supplement comes in easily digestible pellets and is a great source of calcium. Hens instinctively know to take as much of the supplement as their bodies need. It's recommended to place the oyster shell pellets in a separate container from their other feed for best results.

For additional information on this product, please see the Product Documents section for all downloadable user manuals, installation guides, brochures and warranty statements.
