Can chickens eat mustard greens?

Mustard greens are a popular green leafy vegetable packed with nutrients and vitamins. They’re often used as a side dish or added to salads, but can chickens eat mustard greens too? The answer is yes! However, there are some important points to keep in mind when deciding if mustard greens are safe for your chickens.

Eating greens is essential for any chicken’s diet, and mustard greens are no exception. As with all vegetables, moderation is key – mustard greens should only be served as a treat, not a regular part of the diet. This is because they contain high amounts of calcium, which can lead to egg binding if fed in excess.

In addition to calcium, mustard greens have many other beneficial nutrients, such as Vitamin A and Vitamin C. These vitamins help maintain good bird health and boost immunity against common illnesses like colds and flu. Mustard greens also have high water content, which helps keep chickens hydrated during the hot summer.


The benefits of eating mustard greens for chickens

Mustard greens are a nutrient-packed leafy green that can be a great addition to your chicken’s diet. This superfood has all the vitamins and minerals necessary to keep your chickens healthy and happy. Here are five benefits of feeding your chickens mustard greens regularly.

Potential Parasite Prevention

Mustard greens contain high levels of Vitamin C, which is known to boost the immune system in chickens. The increased immunity can help protect them from parasites, which can make chickens very ill if left untreated.

As a bonus, the vitamin C in mustard greens also helps digestion so that your chickens get all the nutrients they need from their food.

Excellent Source of Vitamin K

Mustard greens are an excellent source of Vitamin K, which helps regulate blood clotting in birds. Vitamin K helps with calcium absorption in chickens so that their bones remain healthy and strong.

A lack of calcium can lead to weak eggshells and other related issues in laying hens, so it’s important to ensure that your flock gets enough vitamin K-rich foods like mustard greens.

Packed with Vitamins and Minerals

Mustard greens are full of vitamins and minerals – including Vitamins A and C, folate, iron, magnesium, manganese, phosphorus, potassium, riboflavin, thiamin, and zinc – that help maintain optimum health for your chickens.

These vitamins and minerals help support growth and development while keeping feathers shiny and bright. Plus, they provide an extra dose of protein too.

High Fiber Content

High-fiber foods like mustard greens provide many benefits for chickens by helping them digest food more easily. The fiber content helps keep their digestive systems running smoothly while regulating blood sugar levels.

Feeding your flock plenty of fiber-rich foods like mustard greens will go a long way toward keeping them healthy.

A Natural Pest Repellant

Mustard Greens are natural pest repellants due to their sulfur content. Sulfur is known to repel some common pests like fleas; however, it does not affect internal parasites or mites.

Nevertheless, having a few plants growing near the coop can give you peace of mind knowing you have taken preventative measures against these pesky critters from invading your coop space.

Things to watch out for when feeding mustard greens to chickens

You should keep some things in mind when feeding your chickens mustard greens. Let’s look at three of the most important points to consider when adding this tasty green to your birds’ meals.

Freshness matters

Like all vegetables, mustard greens should be eaten fresh for maximum nutritional value. How can you tell if the greens are still fresh? Look for crisp leaves that aren’t wilted or discolored.

If the leaves appear slimy or limp, it’s best to discard them as they may contain harmful bacteria or parasites that could make your chickens ill.

Don’t overfeed

All food items should be offered in moderation to ensure proper digestion and absorption of nutrients. This is especially true for mustard greens as they contain high levels of oxalic acid, which can bind with essential minerals like calcium and iron in the digestive tract and prevent them from being absorbed by the body.

To avoid any potential mineral deficiencies, limit the number of mustard greens you feed your chickens at once, and ensure they have access to a balanced diet that includes other sources of calcium, such as oyster shell grit or eggshells.

Pesticide exposure

As with any food item you give your chickens, it’s important to check that any mustard greens you feed haven’t been exposed to pesticides or chemicals before feeding them to your birds.

If possible, buy organic produce from a local farmer who doesn’t use chemical fertilizers or sprays on their crops; if not, wash any store-bought produce thoroughly before giving it to your flock.

How often should chickens eat mustard greens?

Mustard greens are a nutritious treat for chickens and can be a great supplement to their diet. However, it is important not to feed them too much of this leafy green. As with any other food, moderation is key – it’s best to feed your chickens these greens as an occasional treat and not every day.

You should also limit mustard greens to no more than 10% of your chicken’s total diet. Too much can cause digestive upset for your feathered friends.

How to prepare mustard greens for feeding to chickens

Mustard greens are a great source of nutrition for your chickens and are easy to prepare. With just a few simple steps, you can feed these nutrient-packed greens to your flock in no time. Here’s what you need to know about preparing and feeding mustard greens to your chickens.

Wash the Greens First

Before adding these greens to your chicken’s diet, you must first ensure that any dirt or debris is washed off. You should always do this before chopping the greens into smaller pieces. It is also important to ensure that any pesticides or other chemicals have been removed from the surface of the leaves.

Fill a bowl with cool water and place the mustard greens in it for several minutes before rinsing them off with cold water.

Chop into Small Pieces

Once the mustard greens are clean, you must chop them up into small pieces. This is important as it makes it easier for your chickens to eat and digest them properly.

The pieces should be around 1 inch in length so they can fit comfortably in their mouths without being too large.

Feed Cooked or Raw

Mustard greens can be fed cooked or raw, depending on your preference and available time for preparation. If you choose to cook the mustard greens before feeding them, steaming is recommended as it helps retain more nutrition than boiling.

Alternatively, you can offer up raw mustard greens as part of their regular diet if desired. Just remember that if you choose this route, only offer up small amounts at a time, as raw mustard greens contain oxalic acid, which can be toxic if consumed in large quantities over extended periods.

Remove Any Uneaten Pieces

Once you have placed the prepared mustard greens in your chicken’s enclosure, check back regularly throughout the day and remove any uneaten pieces before they become spoiled or rotten.

This will help prevent diseases like salmonella and keep things hygienic for yourself and your flock.

Can baby chickens eat mustard greens?

Mustard greens are an excellent addition to any chicken diet, though you should note that baby chickens can’t eat as much as adults. This is because they don’t yet have the fully developed digestive system to process lots of mustard greens properly.

While these little guys can still nibble on a small amount of the leaves occasionally, you should restrict their consumption and make sure they don’t accidentally gorge themselves on them. It’s best to stick with a more balanced diet for infant chickens to ensure that they get all of the necessary vitamins and minerals they require.

What other leafy greens can chickens eat?

If you’re raising chickens, you know that providing them with a balanced and healthy diet is essential for their general well-being. Many chicken owners choose to supplement their feed with leafy greens. Mustard greens are popular choices, but there are other leafy greens your chickens can enjoy. Let’s take a look at some of the options.


Lettuce is a great option for chickens, especially if you have access to organic varieties. It offers several key vitamins and minerals – such as Vitamin K and folate – and fiber, which helps keep chickens regular.

In addition, lettuce contains lutein and zeaxanthin, two powerful antioxidants that help protect against cancer and other diseases. Just make sure to avoid iceberg lettuce; it is mostly water and won’t give your chickens the nutritional benefits they need.

Kale also provides plenty of dietary fiber, which aids digestion in poultry. As with spinach, you should chop it up into small pieces before feeding it to your birds so they can digest it more easily.

It has a slightly peppery taste that most chickens enjoy eating, so this can be a great way to add variety to their diets while still getting all the necessary nutrients they need for good health.

Again like spinach or kale, make sure arugula is chopped up into small pieces before feeding it to your birds so they can digest it properly without any problems.
