Did you know that ducks are omnivores, meaning they eat both plant and animal-based food? In the wild, ducks have a diverse diet that includes insects, snails, small fish, and aquatic plants. In captivity, they are typically fed a mix of commercial feed and fresh produce. However, not all foods are suitable for ducks, and an imbalanced diet can lead to health problems. So, let’s dive deeper into what ducks eat and how to provide them with a nutritious diet.
Fun Facts About Ducks

- Ducks have waterproof feathers that help them stay dry while swimming.
- Some ducks, such as mallards, can fly up to 55 miles per hour!
- A group of ducks on the ground is called a “flock,” while a group of ducks in flight is called a “team” or a “raft.”
- The longest-living duck on record was a mallard that lived for 27 years!
- Male ducks are called “drakes,” while female ducks are called “hens.”
- Ducks have a complex communication system that includes different types of quacks and other sounds.
- Some duck species, such as the Mandarin duck, are known for their vibrant and colorful plumage.
The Natural Diet of Wild Ducks
Wild ducks are omnivorous and eat a variety of foods depending on their habitat and the season. Aquatic plants, insects, and small animals like snails and crustaceans are among the many things that wild ducks eat. Some ducks are adapted to diving for food, while others feed on the surface of the water.

Do All Ducks Eat the Same Thing?
Not all ducks eat the same thing. Different species of ducks have evolved to eat different types of food based on their habitat and diet. For example, dabbling ducks like mallards are primarily herbivorous and feed on aquatic plants and seeds, while diving ducks like scaups and canvasbacks eat more animal matter such as crustaceans and mollusks.
What Do Domesticated Ducks Eat?
Domesticated ducks generally have a diet that is similar to that of their wild counterparts but with the addition of commercial duck feed. This feed is specifically formulated to meet the nutritional needs of ducks and may include grains, seeds, and other ingredients. In addition to commercial feed, domesticated ducks may also be given a variety of fruits and vegetables, such as kale, spinach, lettuce, peas, and carrots. They may also be given insects, such as mealworms, as a source of protein. Overall, it’s important to provide domesticated ducks with a balanced diet to ensure their health and well-being.
Here’s a list of foods that domesticated ducks may eat:
- Commercial duck feed
- Vegetables (e.g. lettuce, peas, carrots, sweet potatoes, squash)
- Fruits (e.g. apples, berries, melons, bananas)
- Insects (e.g. mealworms, crickets, grasshoppers)
- Fish (e.g. canned fish, freeze-dried fish)
- Grains (e.g. wheat, barley, corn, rice)
- Seeds (e.g. sunflower seeds, flax seeds)
- Nuts (e.g. peanuts, walnuts)
- Yogurt (as a source of probiotics)
- Eggshells (as a source of calcium)
- Grit (as a source of minerals and to aid in digestion)
All domesticated ducks may eat all of these foods, and the amount and frequency of each food may vary based on factors such as age, activity level, and health status.
Commercial feed for ducks typically includes a variety of seeds as well as other ingredients to provide a balanced diet. Here are some examples of the types of seeds that may be included in commercial duck feed:
- Cracked corn
- Wheat
- Barley
- Oats
- Sunflower seeds
- Flax seeds
- Millet seeds
Types of Commercial Duck Feed and How to Choose the Right One
Commercial duck feed is a convenient and reliable way to provide domesticated ducks with a balanced diet. There are different types of commercial duck feed available, each formulated to meet the specific nutritional needs of ducks at different life stages and activity levels. Here are some common types of commercial duck feed:
- Starter feed: This type of feed is formulated for ducklings from hatch to about 3-4 weeks of age. It contains high levels of protein and nutrients to support their rapid growth and development.
- Grower feed: This type of feed is designed for ducks between 4-6 weeks and 14-16 weeks of age. It has lower levels of protein and higher levels of other nutrients to support their continued growth and development.
- Layer feed: This type of feed is formulated for adult ducks that are laying eggs. It contains higher levels of calcium and other nutrients needed for egg production.
- Maintenance feed: This type of feed is suitable for adult ducks that are not laying eggs or not actively growing. It has lower levels of protein and other nutrients.
When choosing a commercial duck feed for your ducks, consider their age, activity level, and health status. You can consult with a veterinarian or a poultry nutrition expert to determine the right type of feed and the appropriate feeding amount for your ducks. It’s also important to store the feed in a cool, dry place to prevent spoilage and contamination. Remember, fresh, clean water should always be available for ducks to drink and for digestion.
Feeding Ducks in Captivity: Tips and Considerations
When feeding ducks in captivity, provide them with a clean and safe environment. Ducks should have access to clean water for drinking and bathing, and their feeding area should be kept free of feces and other debris. It’s also crucial to avoid feeding ducks foods that are high in salt or sugar, as these can be harmful to their health.
Ducklings Diet

Ducklings have different dietary needs compared to adult ducks. When they are first hatched, ducklings will survive on their yolk sac for up to 24 hours before they start to eat. After this time, they will need a high-protein starter feed that is specifically formulated for young waterfowl.
The starter feed for ducklings typically contains 18-20% protein and may include ingredients such as soybean meal, corn, wheat, and fish meal. It’s important to provide ducklings with feed that is appropriate for their age to ensure that they receive the nutrients they need for healthy growth and development.
As ducklings grow, their dietary needs will change. At around 3-4 weeks of age, they can start to eat a grower feed that has a lower protein content than a starter feed. The grower feed typically contains around 15-17% protein and may include ingredients such as corn, soybean meal, and wheat.
While ducklings can eat some of the same foods as adult ducks, their digestive systems are not fully developed and they may have difficulty digesting certain foods. It’s best to stick to a diet that is specifically formulated for their age until they are fully mature.
Importance of Fresh Water for Ducks’ Health and Digestion
Water is essential for ducks as they require it for digestion and overall health. It’s important to provide ducks with fresh and clean water for drinking and bathing. In captivity, the water should be changed regularly to prevent contamination and ensure that it is safe for the ducks to consume. It’s also important to monitor their water intake, as ducks need a significant amount of water for digestion. Inadequate water intake can lead to dehydration and health problems, so ensuring that ducks have access to an adequate supply of clean water is crucial for their well-being.
Foods to Avoid: Harmful Foods That Can Harm Your Ducks’ Health
- Bread: While bread is often a popular food to feed ducks, it can actually be harmful to their health. Bread is high in carbohydrates and lacks the essential nutrients that ducks need for a balanced diet. Feeding bread to ducks can lead to malnutrition, as well as a condition known as “angel wing,” which causes the wings to grow abnormally and prevents ducks from flying.
- Processed Foods: Ducks should not be fed processed foods such as chips, candy, or junk food. These foods contain high levels of salt, sugar, and artificial preservatives, which can be harmful to ducks’ health.
- Avocado: Avocado contains a toxin called persin, which can be harmful to ducks and other birds. Feeding avocado to ducks can lead to respiratory distress, weakness, and even death.
- Chocolate: Chocolate contains a chemical called theobromine, which can be toxic to ducks and other animals. Even small amounts of chocolate can cause vomiting, diarrhea, seizures, and other health problems in ducks.
- Citrus Fruits: Citrus fruits such as oranges, lemons, and limes should be avoided, as they contain high levels of acid. Feeding citrus fruits to ducks can cause digestive upset, including diarrhea and vomiting.
