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.

  • Quality calcium supplement suitable for all egg laying chickens
  • Great source of calcium, which is critical for the production of strong, healthy eggshells
  • Supplement has been heat treated for purity
  • Pellet-sized crushed oyster shells are easy for chickens to eat
  • Best when fed to birds in a separate container from the rest of their feed
  • Made in USA
  • 5 lb. package of chicken feed supplement
  • We love chickens and know just what their bodies require - who better to make food for pets than farmers? At Tractor Supply Company, we bring our deep passion for land and animals to the center of our products and services

Great quality.

Most of my girls love this calcium. I mix some of my own ground up egg shells in for the couple that prefer a finer flake. They go through it fairly quick.

A few of my chickens egg shells were so soft, the eggs would sometime get broken right in the nesting box. This solved the problem,no more soft shells!

Good clean, well tolerated product.

Love the fact that there are no big chunks in this product. Girls seem to like it, I have dug in the bag and found no dark pieces or dirt/sand contamination. Really seems to help my ladies lay clean, quality eggs so I guess it gets into their system and does its job. Very happy and do heartily recommend.
