Freezing Method:

Another precaution you can take is to freeze the worms before feeding them to your geese. Freezing is known to kill most parasites, reducing the chances of infestation. However, it’s wise to err on the side of caution and take these steps to protect your geese’s health.

Don’t overfeed

When feeding worms to geese, there are a few important things to keep in mind to ensure their well-being. First and foremost, it’s crucial not to overfeed them. Too many worms can lead to digestive problems for geese. Therefore, it’s best to give them just a small handful of worms at a time. In general, you should not give your geese more than 1/4 cup of worms per day. If you’re unsure about the right amount, it’s better to err on the side of caution and provide them with less rather than more.

By following these guidelines, you can ensure that your geese enjoy a safe and healthy meal. So, the key things to watch out for when feeding worms to geese are overfeeding and being cautious about the quantity you offer to prevent digestive issues and promote their well-being.

Disadvantages of overfeeding worms to geese

Overfeeding geese with worms can lead to several disadvantages, which can be detrimental to their health and well-being:

Digestive Problems:

One of the most significant disadvantages is the risk of digestive problems. Geese have a limited capacity to process a large quantity of worms, and overfeeding can overwhelm their digestive systems. This can result in indigestion, stomach discomfort, and potentially more severe digestive issues.


Overfeeding with worms can contribute to obesity in geese. Worms are high in fat, and excessive consumption can lead to weight gain. Obesity can negatively impact the geese’s overall health, making them less active and more susceptible to various health problems.

Reduced Nutrient Balance:

When geese consume an excessive amount of worms, they may not get a balanced diet. Overreliance on a single type of food can lead to nutrient deficiencies, affecting their overall health and vitality.


Overfeeding can result in wasted worms. Geese may not be able to eat all the worms provided, leading to unnecessary resource wastage.


Overfeeding with worms can lead to increased costs for the goose owner, as worms can be relatively expensive. It’s essential to manage feeding practices to avoid unnecessary expenses.

Do Geese Get Worms and Do They Need Worming?

Geese can indeed get worms, and whether they need worming depends on various factors. A healthy goose with a good diet typically has a strong resistance to parasites, which helps keep them from getting worms. However, if a goose is sick or has a poor diet, it becomes more susceptible to worm infestations.

There are multiple ways geese can become infected with worms, such as through contaminated food, and water, contact with infected feces, or living with other infected poultry. To prevent worm infestations in your goose population, it’s essential to maintain a clean environment, including providing clean food and water.

Infections can occur when geese ingest worm eggs found in other birds’ feces, so it’s crucial to prevent any unsanitary conditions from developing in their animal dens. If feasible, consider keeping geese in separate dens rather than in crowded areas with other birds. Additionally, when introducing new geese or animals to your yard, worming them is advisable, reducing the risk of infestation significantly.

For free-range and wild geese, the risk of worm infestations is lower, especially if they are not on overstocked land. However, they often share environments like large ponds with other poultry and bird populations, such as ducks, making complete isolation challenging in such cases. Therefore, maintaining cleanliness and preventive measures remains crucial to managing the risk of worm infestations in geese.


Can Baby Geese Eat Worms?

Yes, baby geese, also known as goslings, can eat worms. It’s important to ensure they have a well-balanced diet to receive the necessary nutrients for proper growth and development. Goslings typically mimic their parents’ dietary habits, so if you observe adult geese eating worms, their chicks will likely do the same.

Worms are a valuable source of protein for baby geese, so it’s recommended to provide them with opportunities to consume worms. You can achieve this by placing a dish of worms near their feeding area or by scattering them in the yard. However, when scattering worms, be sure to supervise the process, as baby geese can potentially choke on worms that are too large. Additionally, remember to complement their diet with other appropriate foods for their well-being.

Do Geese Eat Mealworms?

Yes, geese do eat mealworms. Mealworms, which are the larval stage of the darkling beetle, are a common food source for many animals, including geese. While geese are known to consume insects, larvae, and small amphibians, they have a preference for mealworms. Mealworms are not only readily available in their diet but also offer essential nutrition, including protein and fat. Additionally, mealworms are relatively high in calcium, which is crucial for bone development. Due to these factors, mealworms make up a significant portion of the diet of many wild geese.

Can a Goose Eat Army Worms?

Yes, geese can indeed eat armyworms. Armyworms are the caterpillars of certain types of moths, and while they are typically considered pests that can harm plants, they can serve as a valuable food source for geese. Geese are known to feed on various insects and small invertebrates, including armyworms, as part of their natural diet. So, if you’re concerned about armyworms damaging your plants, allowing geese to forage in your area can help control the pest population and provide a natural solution to managing this issue.


Do Canada Geese Eat Worms and Mealworms?

Canada geese, specifically Branta canadensis, are omnivores, which means they consume a variety of foods. This includes earthworms and mealworms, in addition to other animals such as small fish, amphibians, and reptiles. So, yes, Canadian geese do eat worms and mealworms as part of their omnivorous diet.

How Do You Deworm a Goose?

To deworm a goose, first, identify signs of infestation such as lethargy and abnormal feces. Consult a veterinarian for a tailored deworming plan, considering medications like Panacur, Ivermectin, or Flubenvet. Follow the vet’s instructions for administering the dewormer and closely monitor the goose for signs of improvement, acknowledging that the severity of infection can still pose risks, as noted in the content. Additionally, consider a preventative deworming schedule to maintain the goose’s health. Always seek professional guidance for the best approach to deworming your goose.

How often can geese eat worms?

The frequency with which geese eat worms can vary based on several factors. Geese are generally herbivores, but they may occasionally consume small invertebrates like worms. The frequency of this behavior is influenced by the availability of other food sources. If plants are abundant, geese will rarely eat worms. However, if plants are scarce, they may turn to worms as a more frequent source of food.

Additionally, young goslings are more likely to eat worms than adult geese. This is because goslings require a higher protein intake to support their rapid growth. Therefore, the frequency of geese eating worms depends on various factors, including the availability of plants and the age of the geese. It is not a fixed or constant behavior, but rather one that is influenced by their immediate environment and nutritional needs.

Can geese eat insects?

Yes, geese can eat insects. While geese are primarily herbivores and their diet mainly consists of plants and grasses, they are known to consume small invertebrates, including insects, on occasion. This behavior is more likely when other food sources are limited, and the availability of insects becomes a supplementary source of nutrition for them. So, while geese are not strict insect-eaters, they are opportunistic and may include insects in their diet when necessary.
