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

My hens like it

10 years ago
My hens free range and are great foragers. I keep their feeder filled with layer crumbles, but I worried that they wouldn't get enough calcium if they are mainly eating stuff in the yard. Also, there are times when I'm integrating youngsters into the flock and everyone has to eat chick feed until the pulleys are old enough to lay eggs. So I keep a container filled with this oyster shell available. The hens do eat it and I haven't had any eggs with thin shells.

Steel wool pieces

8 years ago
I found fuzzy blobs of steel wool pieces in my 5-pound bag of DuMOR Oyster Shell. Not a lot but enough to have me spreading out the product and picking through before I put it out for my girls. There is a thread on the Backyard Chickens forum talking about this right now and it seems it's also an issue with the Manna Pro brand and it looks like DuMOR and Manna Pro might be from the same suppliers? It seems that steel wool is used to scrub the shells during processing and some of it comes off and gets mixed with the end product. I'm not sure what the health implications are here but it's a little disturbing to see this when you're pouring out the oyster shell. I will be looking for another source of oyster shell in the future.

Calcium to remedy soft and no shell eggs

11 days ago
I had a duck that was not laying eggs with hard shells. A local fowl supplier told me that I needed to supplement my layer's diet with calcium supplement so that she would stop laying soft-shelled and no-shell eggs.
