What do Ducks Normally Eat?

Ducks are omnivores and their diets often vary depending on their habitat and the availability of food sources. While they’re popularly known for their love of bread and crackers at local ponds, these foods aren’t necessarily the best for their health.

Natural Diet in the Wild

In the wild, ducks consume a varied diet, which is crucial to meet their nutritional needs:

  • Aquatic Plants: This makes up a significant portion of a duck’s diet. They often graze on the surface or dive to eat underwater vegetation.
  • Seeds and Grains: Ducks consume various seeds and grains, which they find while foraging on land or in the water.
  • Insects and Small Fish: They also consume insects, small fish, and their larvae, providing them with essential proteins.

Feeding Ducks in Captivity

When it comes to domesticated ducks or those in captivity, the diet can be more controlled and should ideally mirror the variety found in the wild diet. Some of the common foods given to ducks include:

  • Duck Pellets: These commercially produced pellets are nutritionally balanced to provide the necessary nutrients to ducks.
  • Vegetables and Fruits: Ducks can eat a variety of fruits and vegetables, including peas, leafy greens, and non-citrus fruits, which should be cut into small pieces.
  • Worms and Insects: Worms, mealworms, and insects can be a good source of protein.

With this information in mind, one might wonder about the place of worms in a duck’s diet. Can ducks eat worms? If so, what types of worms, and what is the impact on the duck’s health? We’ll delve into these queries in the upcoming sections.

Can Ducks Eat Worms?

The straightforward answer to the question “Can ducks eat worms?” is yes. Worms, specifically earthworms, are a natural part of a duck’s diet, especially for those living in the wild. Worms provide essential proteins and nutrients that are beneficial for ducks. However, the type of worm and its source can significantly affect the health impact on the duck, making this a slightly more complex issue.

Earthworms and More

Ducks can eat various types of worms. Earthworms are the most common type and are found in virtually every corner of the globe. Ducks will naturally forage for these worms, especially after a rain when the worms come to the surface.

Beyond earthworms, ducks may also eat other types of worms if available. These could include mealworms, waxworms, and even silkworms. Mealworms, in particular, are a popular choice for those raising ducks, as they can be easily purchased from pet or farming supply stores.

Worms from Safe Sources

While worms are a beneficial food source for ducks, it’s crucial to consider the source of these worms. Worms that come from contaminated soil or water, such as areas with high pesticide use or polluted bodies of water, can carry toxins that are harmful to ducks. Therefore, if you’re considering feeding worms to your domesticated ducks, ensure they are sourced from safe and clean environments.

Mealworms or earthworms that are commercially grown and sold as pet food are typically a safe choice, as they are often raised in controlled conditions and are free from harmful substances.

Moderation is Key

Although worms can be a healthy part of a duck’s diet, they should be fed in moderation. Overfeeding worms can lead to an unbalanced diet, as ducks may refuse other foods. Worms should ideally be used as a treat or supplement to the diet rather than the main food source.

How Do Worms Impact Ducks’ Health?

Incorporating worms into a duck’s diet can have a range of impacts on their health, both positive and negative. It’s important to remember that balance is key in any diet, and this principle applies to feeding worms to ducks as well.

Nutritional Benefits

Worms, especially earthworms and mealworms, are rich in protein, an essential nutrient for ducks. Protein aids in their growth, feather production, and overall body functions. Worms also contain other nutrients like vitamins and minerals. For example, earthworms are a source of calcium, which is crucial for egg-laying ducks to produce strong eggshells.

Potential Risks

While worms can provide many benefits, they also come with potential risks. One of the primary concerns is the risk of parasite transmission. Worms can be intermediate hosts for various parasites and can pass these onto the ducks that eat them. Parasites can cause a range of health problems, from minor digestive discomfort to serious illness.

Furthermore, as mentioned earlier, worms from contaminated sources can carry harmful toxins. Therefore, the source of the worms is a vital consideration in feeding them to your ducks.

Balance and Variety

An important factor in feeding ducks is to maintain balance and variety in their diet. Over-reliance on a single food source, including worms, can lead to nutritional imbalances. Feeding a varied diet, including a mix of greens, grains, duck pellets, and worms, can help ensure that ducks receive all the necessary nutrients.

Feeding Ducks Worms: Pros and Cons

Feeding worms to ducks is a common practice, especially for those raising ducks at home. However, like any dietary choice, this practice comes with its advantages and disadvantages. Let’s delve into the pros and cons of feeding worms to ducks.


  1. Nutrient-Rich: As mentioned earlier, worms are packed with essential nutrients like proteins, vitamins, and minerals, contributing positively to a duck’s health.
  2. Natural Food Source: Worms are a part of a duck’s natural diet in the wild. They enjoy foraging for worms and the activity helps to fulfill their instinctual behaviors.
  3. Treat or Reward: Worms can be used as a treat or reward during training. Ducks love them, and they can be an effective motivational tool.


  1. Risk of Parasites: Worms can carry parasites, which can lead to health problems for the ducks. It’s essential to source worms from reliable, clean sources to mitigate this risk.
  2. Potential for Overfeeding: Ducks love worms, and there’s a risk they may choose worms over other foods. Overfeeding worms can lead to a lack of dietary balance, which can cause nutritional deficiencies.
  3. Can Be Costly: If you’re purchasing worms, especially specialty types like mealworms, the cost can add up over time.

The Middle Ground

Given the pros and cons, it’s clear that while worms can be an excellent addition to a duck’s diet, they should be fed responsibly. Ensuring worms are sourced from a safe place, feeding them in moderation, and maintaining a balanced diet with a variety of food sources are all key factors in feeding ducks worms effectively and safely.

How to Feed Ducks Worms Safely?

Having established that worms can be a healthy and enjoyable part of a duck’s diet when properly sourced and fed in moderation, let’s go through the steps to feed ducks worms safely.

Step 1: Source Worms Responsibly

The first step is to ensure that the worms are sourced from a safe and reliable place. If you’re collecting worms from the environment, ensure that they are from an area free of pesticides, pollutants, and other potential contaminants. Alternatively, consider purchasing worms from a reputable supplier who guarantees they are safe for animal consumption.

Step 2: Store Worms Properly

Once you have the worms, they need to be stored correctly until feeding time. Earthworms and mealworms can be stored in the refrigerator for a few days. Ensure they’re kept in a container with ventilation and some soil or peat moss for earthworms, or bran or oatmeal for mealworms.

Step 3: Feed Worms in Moderation

When it’s time to feed your ducks, remember that worms should only make up a small portion of their diet. It’s recommended that worms only constitute about 5% to 10% of the total food intake. If you’re using worms as a treat or reward, give them sparingly to avoid overfeeding.

Step 4: Observe Your Ducks

Always monitor your ducks after introducing a new food into their diet. Look for any signs of discomfort, changes in behavior, or changes in their droppings. If you notice anything unusual, consider consulting with a vet.

Step 5: Maintain a Balanced Diet

Finally, remember to feed a balanced and varied diet. Along with worms, ducks should also consume greens, grains, and commercially available duck feed. This ensures they’re receiving all the necessary nutrients for their health and well-being.

Feeding worms to ducks can be a rewarding experience, providing additional nutritional benefits and satisfying their natural foraging instincts. But like any aspect of caring for an animal, it requires care, attention, and a commitment to their overall health.
