Can Ducks Eat Oyster Shells?


Yes, ducks can eat oyster shells, and in fact, oyster shells can be a beneficial supplement for them, especially for laying ducks.

Oyster shells are a great source of calcium, which is crucial for eggshell formation and the overall bone health of ducks.

Here’s how oyster shells can be helpful:

  1. Strong Eggshells: For laying ducks, a sufficient calcium intake is essential to ensure strong, healthy eggshells. A lack of calcium can lead to weak shells or even egg binding, a condition where the duck has difficulty laying eggs.
  2. Bone Health: Calcium is also important for the overall skeletal health of the ducks, not just the laying ones.

However, there are some points to consider:

  1. Size Matters: It’s important to provide oyster shells in a crushed or pellet form. Whole oyster shells can be too large and hard for ducks to eat.
  2. As a Supplement: Oyster shells should be offered as a supplement, not as a primary food source. They can be scattered in a separate dish or mixed with their feed so ducks can consume them as needed.
  3. Especially for Layers: Non-laying ducks and drakes (male ducks) don’t require as much calcium as laying ducks. Therefore, the provision of oyster shells is particularly beneficial and generally more necessary for laying ducks.
  4. Fresh Water: Always ensure that ducks have access to plenty of fresh, clean water, especially when offering them calcium supplements like oyster shells.

In summary, while ducks can eat and benefit from oyster shells, it’s important to offer them appropriately (crushed or pellet form) and as a part of a balanced diet, especially for laying ducks to ensure they have the calcium they need for egg production and bone health.
