Average Weight of Ducks

Ducks come in all shapes and sizes, and their weight varies significantly depending on factors like breed, age, and overall health. In this section, we will explore the average weight of ducks and how it differs among various breeds and at different ages.

Differences in Breeds

There’s a wide range of duck breeds, each with its unique weight range. Here’s a brief overview of some common duck breeds and their average weights:

  • Mallard: 2.4-3.6 pounds (1.1-1.6 kg)
  • Pekin: 8-11 pounds (3.6-5 kg)
  • Khaki Campbell: 4-4.5 pounds (1.8-2 kg)
  • Muscovy: 6.6-15 pounds (3-6.8 kg)
  • Indian Runner: 3.3-5 pounds (1.5-2.3 kg)

Remember that these are just average figures, and it’s normal for individual ducks to vary in weight, even within the same breed.

Age Factor

A duck’s age also plays a significant role in its weight. As ducks grow and mature, they will naturally gain weight. Young ducklings usually weigh a few ounces, and their weight increases rapidly during the first few weeks of life.

For instance, a Pekin duckling might weigh around 8 ounces (227 grams) at one week old, but by 8 weeks, it could easily weigh over 6 pounds (2.7 kg). It’s essential to monitor your duck’s growth and ensure they gain weight at a healthy pace.

To sum up, ducks’ weight can vary greatly depending on their breed and age. By understanding these factors, you can better care for your ducks and ensure their health and well-being.

Factors That Affect The Weight


A duck’s diet plays a significant role in determining its weight. Ducks are omnivores, and their food sources can include insects, seeds, plants, and even small fish.

You’ll find that ducks living near ponds, lakes, or rivers may feed on more diverse food items than those in urban environments. A balanced diet for your ducks can ensure they maintain a healthy weight and avoid excessive weight gain.


A duck’s habitat can directly influence its weight. If a duck lives in a clean, healthy environment with plenty of space, it is more likely to maintain a balanced weight.

In contrast, waterfowl living in overcrowded or polluted areas may suffer from poor nutrition, leading to weight problems. Keep an eye on your ducks’ surroundings and aim to create a conducive living space for their optimum health.

Mating Season

During the mating season, ducks may experience fluctuations in their weight. Male ducks, or drakes, tend to put on extra weight in preparation for attracting a mate, while female ducks may lose weight as they focus on nesting and laying eggs. It’s essential to be aware of this seasonal variation in weight and understand that it’s a natural part of the duck’s life cycle.

When you come across baby ducks, also known as ducklings, they appear so small and fragile. Their weights can vary depending on the breed, but let’s look at some general numbers to give you an idea.

At birth, most ducklings typically weigh around 40-50 grams. In the first week of their lives, you’ll notice that they grow rapidly, almost doubling in size. By the end of the week, they can weigh about 80-100 grams.

During the second week, your baby ducks will continue to grow at an impressive pace. Their weights might increase to around 150-200 grams. Providing them with proper nutrition and care during this crucial time is essential.

As the baby ducks reach the third week, they’ll gain more weight steadily. At this stage, they might weigh between 250 and 350 grams. Ensuring they have adequate living space is important, as they will continue growing from here.

Remember, these are just general numbers, as the actual weight of baby ducks can vary based on factors such as breed, genetics, and individual growth rates. Providing a safe and nurturing environment with proper nutrition will support your ducklings in reaching their optimal growth.

Methods of Weighing Ducks

Weighing ducks is crucial to understanding their health, growth, and nutritional needs. In this section, you’ll learn about several common methods for weighing ducks.

The first method uses a digital scale designed for birds and other animals. Typically, these scales have a flat platform where you can place your duck comfortably. Choose a scale with the appropriate weight capacity and sensitivity to provide accurate measurements. To make the process easy and stress-free for your duck, follow these steps:

  1. Turn on the scale and allow it to zero out.
  2. Gently place the duck on the scale’s platform.
  3. Maintain a calm environment to keep the duck still.
  4. Record the weight displayed on the scale.

The second method is using a weighing sling or harness. This can be especially helpful if you’re working with larger ducks or want to weigh them while they’re suspended. Use a scale with a hook that is specifically designed for this purpose. Here’s how to properly use a weighing sling:

  1. Set up a sling or harness according to the manufacturer’s instructions.
  2. Securely fasten the duck into the sling or harness.
  3. Attach the scale’s hook to the sling or harness.
  4. Lift the duck and ensure it’s fully suspended.
  5. Note the weight shown on the scale’s display.
