Ducks are often depicted in popular culture as eating bread, but this is an unhealthy practice that can lead to malnutrition and other health issues. While ducks can forage for insects, plants, and other food sources, they are often fed by humans. Overfeeding waterfowl can cause problems such as dependence on handouts and nutritional imbalances. Ducks cannot properly digest dairy products like cheese, which can be harmful to their health. It is best to avoid feeding ducks cheese and provide them with vegetables, grains, and other natural food sources instead.

What You'll Learn

Ducks cannot digest dairy products
Ducks are unable to properly digest dairy products. While they love getting treats, leftovers, and supplemental foods, dairy items like cheese cubes or ice cream are not safe for them. Ducks don't need human-provided snacks; they are capable of foraging for insects, plant life, and other nutrition sources on their own.
In fact, overfeeding waterfowl like ducks can cause a host of problems, from teaching them to rely on handouts to throwing off their natural nutritional balance. It's best to avoid feeding ducks any dairy products, bread, or highly processed foods. Even though bread is made from grains, the bread-making process renders it very filling with a relatively low amount of nutrients.
Ducks will also struggle to digest salty or sugary snacks, citrus fruits, spinach, avocado plants, and raw eggs. Most fruits are safe for ducks to eat, but fruits with seeds like apples and pears, and pits like cherries, plums, peaches, and apricots can be dangerous. These fruits can still be fed to ducks, but the seeds and pits must be removed first as they contain small amounts of cardiac-toxic cyanide compounds which can be fatal.
Ducks can eat vegetables, but these should be cut into small pieces before being fed to them, as ducks don't have teeth. Good options include salad greens, vegetable peels, nuts, grapes, peas, corn niblets, and carrot pieces. Ducks can also eat grains like oats, rice, and seeds.

Cheese is nutritionally poor for ducks
While it may be tempting to feed ducks cheese, especially if they are eagerly approaching you for food, it's important to understand that cheese is nutritionally poor for ducks and can even be harmful.
Ducks are perfectly capable of foraging for insects, plant life, and other nutrition sources on their own. They have specific dietary requirements that include a variety of plants and animals they find while foraging. However, cheese is not an appropriate food item for them.
Cheese, being a dairy product, is something ducks can't properly digest. It falls under the category of processed "human" food, which is not suitable for waterfowl. Ducks have their own natural nutritional balance, and feeding them cheese can disrupt that balance.
Instead of cheese, there are several healthy alternatives that you can feed ducks. It is recommended to imitate the types of food they naturally eat in ponds and fields, such as vegetables and nutritious grains. For example, a bag of frozen mixed peas, corn niblets, and carrot pieces is a nutritious and affordable option.
It's important to prioritize the ducks' health and well-being by providing them with food that meets their nutritional needs. While they may seem eager for cheese or other human snacks, it's best to stick to foods that support their natural diet.

Ducks can forage for their own food
Ducks are perfectly capable of foraging for their own food. They can find insects, plant life, and other nutrition sources without human help. That means it's not necessary to feed ducks in parks, and overfeeding waterfowl can cause a host of problems, from teaching them to rely on handouts to throwing off their natural nutritional balance.
If you do want to feed ducks, it's important to know what they can and can't eat. Ducks can eat vegetables, grains, and fruits, but they should be cut into small pieces as ducks don't have teeth. Good options include frozen mixed peas, corn niblets, and carrot pieces, as well as grains like oats, rice, and seeds. Ducks can also eat most fruits, but not fruits with seeds or pits, as these can contain cardiac-toxic cyanide compounds. Vegetables in the nightshade family, such as eggplants, peppers, potatoes, and tomatoes, should be avoided, as they can be toxic to ducks. Other foods to avoid include bread, dairy products, salty or sugary snacks, and citrus fruits or spinach, as these can hinder calcium absorption.
Some sources note that ducks will generally avoid eating things that are bad for them. For example, while avocado plants are toxic to ducks, one source notes that ducks will avoid eating them. Similarly, while unripe tomatoes are high in solanine and should be avoided, there are many anecdotes of ducks barely nibbling on tomato plants or avoiding them altogether.
In general, it's best to avoid feeding ducks "human" food and to stick to things they would naturally eat in the wild, such as vegetables, grains, and fruits.

Cheese is not toxic to ducks
While cheese is not toxic to ducks, it is still not safe to feed to ducks and other waterfowl. Ducks cannot digest dairy products properly. It is best to feed ducks vegetables and nutritious grains, while processed "human" foods should be avoided. Ducks are perfectly capable of foraging for insects, plant life, and other nutrition sources on their own. Overfeeding waterfowl can cause a host of problems, from teaching them to rely on human handouts to throwing off their natural nutritional balance.
When it comes to treats, it is important to practice moderation. Treats or table scraps should only make up about 10-15% of a duck's diet; the rest should be good-quality feed suitable for the type of bird. It is also important to note that some foods are not safe to feed ducks and can pose a serious threat or even be fatal. For example, raw meat should not be given to ducks as it can carry the risk of salmonella and other harmful bacteria.
Additionally, while ducks can eat eggs, they should be cooked. Raw eggs may entice them to start eating their own eggs, which is a difficult habit to break. The leaves of avocado plants and the pits and skin of avocados contain a toxin called persin, which can be fatal for ducks. Most fruits are safe to give to ducks, but fruits with seeds like apples, pears, cherries, plums, peaches, and apricots should be avoided or given without the seeds and pits, as they contain small amounts of a cardiac-toxic cyanide compound that can be fatal.
In terms of vegetables, while ducks can eat pepper plants, it is recommended to avoid feeding them large amounts of pepper leaves if they don't have other greens to choose from. Tomato leaves should also be avoided as they contain solanine, which is toxic to ducks. Instead, vegetables like cut salad greens, vegetable peels, nuts, grapes, and other small produce can be offered to ducks, ensuring that the pieces are small enough for them to handle.

Ducks can eat some human food
While it is not recommended to feed ducks human food, there are some human foods that ducks can eat. Ducks are perfectly capable of foraging for insects, plant life, and other nutrition sources on their own. However, if you want to feed them human food, it is important to know what they can and cannot eat.
Ducks should not be fed any dairy products, such as cheese or ice cream, as they cannot digest these properly. Bread and other bread products, such as crackers and donuts, are also not suitable for ducks, as they have low nutritional value and can lead to poor health. Similarly, salty or sugary snacks, as well as highly processed foods, should be avoided.
On the other hand, ducks can eat certain vegetables and fruits. Vegetables like lettuce, cabbage, broccoli, cauliflower, carrots, and peas are safe for ducks to consume. Fruits such as grapes, berries, and apples (without the seeds) can also be fed to ducks, but only in small amounts as treats, as they are high in sugar and carbohydrates and lack protein and fat.
It is important to note that while ducks may enjoy eating human food, their diet should primarily consist of food they naturally eat, such as insects, plants, and grains. Overfeeding ducks human food can disrupt their natural nutritional balance and teach them to rely on human handouts instead of foraging for themselves.
