Do yours chickens need more calcium in their diet? Look no further. Our pebbled sea shell blend is perfect source of calcium. The larger pebbled provide a 24-hour supply of calcium that is release slowly.

  • Gives the calcium boost your layers need.
  • Larger pebbled pieces provide 24-hour release of calcium. 
  • Increases strength of eggshells. Healthier chicken = better egg quality.


Did you know that chicken calcium has different purposes?

Layer feed calcium: fast-release. (The calcium breaks down quickly. And while this is super important to hen health, it can become useless after hens have eaten and if they’re forming their eggs during the night.)

Oyster shell calcium: slow-release. (The calcium breaks down over time so our hens can use it when they really need to, for their eggshells.)

Hens go through a pretty amazing process building eggs, and oyster shell helps out at a very specific point. The shells are built last, usually overnight, and the process can drain your chicken of calcium. The calcium in oyster shell is digested at a different rate than that found in their feed, so they have some extra during those night hours when they are creating shell. Help them out by providing oyster shell at all times, and they will self-regulate, eating it when they need it.

Oyster and sea shell should always be available to our laying hens in a separate dish than their feed… our chickens have different calcium needs and will eat as much as they need. Don’t worry… it’s true!
