Chickens consume almost everything, from grains to crawling insects. But what about cauliflower?

Like most cruciferous vegetables, cauliflower is rich in essential nutrients, which benefit people and animals. What’s more, this all-purpose vegetable is versatile, and you can grow it in your backyard.

In this guide, we embark on a culinary journey to determine if cauliflower is suitable for your flock. We will explore the benefits and potential risks of this vegetable. Plus, provide you tips on how to incorporate it into your chicken feed.

Can You Feed Cauliflower to Your Chickens?

Chickens have a unique digestive system that can handle a variety of foods. So, it’s no surprise for your feathered friends to indulge in this cruciferous delight. However, this vegetable is best given to chicken as a snack but not as part of the main diet.

In moderation, cauliflower can be an excellent source of nutrition for your chickens. But if you overfeed them, the vegetable could cause digestive problems like vomiting and diarrhea because of its high fiber content.

Cauliflower is also rich in sodium, which could be toxic to your birds when consumed in large quantities. Besides that, it contains goitrogenic compounds that can affect thyroid hormones, causing goiter development.

That said, chickens can eat all parts of cauliflower, including its leaves, florets, and stems. That means your birds can help you dispose of those scraps from the various parts of the vegetable you don’t use in the kitchen.

It’s best to chop the parts into small chunks to avoid cases of choking, especially in baby chickens. You also want to remove residual pieces to avoid attracting bacteria and pests.

But before feeding your birds the cauliflower scraps, check if your country has placed restrictions on kitchen scraps. In the UK, for instance, it’s a crime to feed chickens with kitchen leftovers unless you come from a vegan household.

As you can see from the table above, cauliflower comes packed with lots of beneficial nutrients. Now let’s see how these nutrients help improve the chicken’s health.


It’s no secret that protein is a primary constituent of the biologically active compounds in the chicken’s body. Besides promoting growth, it helps in egg production, feathering after molting, and improving immunity.

While cauliflower provides chickens with protein, it’s not enough to meet the dietary requirement of chickens. Therefore, consider supplementing it with protein-rich feeds like sunflower seeds or soybeans.


Carbohydrates are an important part of the chicken’s diet because it’s necessary for energy production. They also play a vital role in supporting metabolic functions by maintaining the proper functioning of organs like the liver and brain. Additionally, carbohydrates help in the utilization of other nutrients by the body.

Like protein, cauliflower contains negligible amounts of carbohydrates. Therefore, it cannot meet your flock’s carbohydrate requirement. Nonetheless, you can give your chicken this vegetable as a treat after they’ve consumed food rich in carbohydrates like oats, millet, barley, etc.


Lack of sufficient vitamins in a chicken’s diet could lead to several health problems and sometimes death. By giving your chickens vegetables, like cauliflower, they can receive Vitamin C, Vitamin K, and Vitamin B6.

  • Vitamin C

Like humans, chickens need vitamin C or Ascorbic acid. Vitamin C helps to support the immune system and shield cells against oxidative damage. In addition, it helps the bird process proteins and lipids.

  • Vitamin K

Vitamin K from cauliflower helps in blood clotting, preventing chickens from bleeding to death when bruised or injured. It also boosts blood circulation and contributes to the development and maintenance of healthy bones. Besides cauliflower, chickens can get Vitamin K from leafy greens like kale, spinach, lettuce, etc.

  • Vitamin B6

Another vitamin chickens can enjoy from this vegetable is Vitamin B6 or pyridoxine. It facilitates growth and development and improves the bird’s health. It also helps in protein metabolism and neurotransmitter synthesis. A deficiency of Vitamin B6 leads to retarded growth, anemia, and dermatitis. Other healthy foods that contain this nutrient include grains, legumes, and meats.


In addition to vitamins, cauliflowers come packed with micro and macro minerals, including:

  • Calcium

Chickens require calcium to lay eggs with strong eggshells and develop healthy bones. Although cauliflower has negligible amounts of calcium, it can still help prevent calcium deficiency in your birds.

  • Phosphorous

Phosphorous is the major component of organic compounds. It’s responsible for lipid transportation, fat metabolism, and nervous tissue metabolism in chickens. Phosphorous works with calcium to promote bone formation and optimal skeletal development. It’s also a constitute of eggs.

  • Magnesium

In chickens, magnesium is essential for bone development, muscle functions, and the transmission of nerve signals. In addition, the mineral is a co-factor for enzymes involved in energy production and digestion.

  • Potassium

Potassium works to support normal laying hen performance. Moreover, the mineral maintains the hen’s homeostasis by balancing fluids in the cells and regulating osmotic pressure. As a result, it ensures continuous hydration and proper cell function. Potassium is also important for nerve function and proper muscle function.

  • Manganese

Manganese is a trace mineral essential for metabolic processes in the chicken’s body. It is also an integral part of bone development, eggshell formation, wound healing, and prevention of perosis.

  • Iron

Cauliflower also provides chickens with iron, which maintains healthy blood circulation. Laying hens, in particular, require this mineral for egg production and to prevent anemia. While layer feeds come with sufficient iron levels, it doesn’t hurt to supplement the diet with iron from this healthy vegetable.

  • Folic Acid

Last but not least, cauliflower provides chickens with a good amount of folic acid. Also referred to as Vitamin B9, folic acid is vital for cell growth and development in chickens. It comes in handy during periods of rapid growth, like the development of eggs or growth in chicks.

It also aids in red blood cell production, nutrient metabolism, and the proper functioning of the immune system. If chickens don’t receive enough folic acid, they will lose feathers. Their combs and wattles will also become pale and egg production will reduce.

Now, let’s highlight the various health benefits of feeding chickens cauliflower.

Excellent Source of Fiber

Cauliflower stands out from other vegetables because of its high dietary fiber content. While chickens don’t digest dietary fiber, it helps to improve their health and well-being.

Dietary fiber helps to improve the chicken’s digestive system. It achieves this by stimulating proper gastrointestinal tract motility and preventing constipation. Furthermore, it adds a mild abrasive action in the tract, keeping the digestive system clean and blockage free.

Another benefit of dietary fiber is that it slows down digestion in the gut to enhance nutrient absorption. As a result, it contributes to the growth and development of chickens.

If that is not enough! The fiber promotes the growth of beneficial bacteria in the chicken’s gut and helps maintain its balance. A balanced gut environment translates to effective nutrient absorption and increased immune function.

Rich in Antioxidants

Green cauliflower leaves are rich in antioxidants, like carotenoids and flavonoids. Although often overlooked by some poultry owners, antioxidants play an important role in chickens.

These compounds protect chicken cells from damage caused by free radicals. These radicals develop as by-products of cellular processes or environmental stressors.

And the interesting part:

They facilitate the production of immune cells and antibiotics, which respond to infections in the body. Antioxidant promotes the efficient functioning of the immune system and increases resistance to diseases.

Other Food Worth Considering

Food Chickens Should Not Eat

As said earlier, chickens can eat almost everything. However, certain foods are not good for their health, including:

Bottom Line

From the information above, it’s quite clear chickens can eat cauliflowers, but in moderation. If you overfeed them, they might experience digestive discomforts or diarrhea. This happens because chickens cannot digest the high dietary content of this vegetable.

Despite this, chickens can enjoy some health benefits from cauliflower, such as improved digestion and immune system. Let’s not forget the essential nutrients, like proteins, minerals, vitamins, and carbohydrates.

The best way to feed chickens cauliflower is to chop them into smaller chunks. This way, you can prevent cases of choking, particularly in baby chicks.

Alternatively, you can tie a rope around the vegetable and hang it in the chicken coop so your chickens can peck at it at their pleasure. You can also boil the cauliflower to reduce harmful compounds like sodium and goitrogenic.

Overall, cauliflowers make healthy snacks for chickens, regardless of age or breed.
