What is Asparagus?

Asparagus is a spring vegetable that comes from the perennial asparagus plant. It has green shoots that emerge from the ground as spears.

There are three main types of asparagus:

  • Green asparagus – This is the most common variety. It has green spears and a delicate flavor.
  • White asparagus – Grown underground to prevent photosynthesis, giving it a white color. It has a mild taste.
  • Purple asparagus – Has a fruity, sweet flavor and tends to be smaller and more tender.

Wild asparagus grows in coastal areas and marshlands, while modern commercial asparagus is a cultivated crop.

Can Chickens Eat Asparagus?

Yes, chickens can safely eat asparagus. In fact, it provides some great nutritional benefits similar to other vegetables.

Asparagus is not toxic or poisonous to chickens in any way. It does not contain oxalates or other anti-nutrients that can be harmful.


Chickens tend to enjoy the flavor of tender young asparagus spears. Both the spears and leaves of the plant can be fed to chickens.

Is Asparagus Safe For Chickens?

When fed properly, asparagus is completely safe for chickens to eat. However, there are some precautions to take:

  • Only feed chickens the young spears and leaves, not the tough, woody parts of the plant.
  • Introduce asparagus slowly and in moderation to avoid digestive upset.
  • Never feed chickens rotten or moldy asparagus.

Can Chickens Eat Purple Asparagus?

The purple variety tends to be smaller in size but can still be fed to chickens safely in moderation. It provides vibrant antioxidants.

Can Chickens Eat Cooked Asparagus?

Cooked asparagus is soft and easy for chickens to digest. Lightly steaming or roasting retains the nutrients. Avoid adding any seasonings.

Can Chickens Eat Asparagus Raw?

Chickens can eat raw, fresh asparagus spears as part of their diet. This preserves the full vitamin and antioxidant content.

Can Chickens Eat Whole Asparagus?

Chickens can eat the whole young asparagus stalks, including the tips and spears. However, the tough, fibrous bottom portion and woody stems should be removed before feeding.

The tender top 3/4 of asparagus spears can be fed whole to chickens. Chopping into smaller pieces may encourage chickens to eat more.

What Parts of Asparagus Can Chickens Eat?

Chickens can safely eat:

  • Young tender spears
  • Leaves and ferns
  • Florets and flower buds

Avoid feeding chickens:

  • Old, tough asparagus stems
  • Roots
  • Any rotting or wilted parts

Remove any dried out or woody portions which are difficult to digest. Only offer the tender parts of the asparagus plant.

Can Chickens Eat Asparagus Plants?

Chickens should not free-range on an active asparagus patch, as they may damage the developing spears. However, spent plant material can be fed to chickens.

Trimmed stems, leaves, stalks and tops that are removed when harvesting spears make a nutritious treat. Avoid letting chickens overgraze plants.

Can Chickens Eat Asparagus Seeds?

Asparagus plants produce red berries that contain seeds. Chickens can eat the berries and seeds in moderation.

The berries provide protein, fat and fiber. They can be fed as the occasional treat but won’t provide substantial nutrition.

Can Chickens Eat Asparagus Stems?

The bottom tough, woody stems should be trimmed off before feeding asparagus to chickens. However, the tender upper green stems are fine for chickens to eat.

Chop the stems into smaller pieces to allow chickens to digest them easier. The young shoots will be gentler on their digestive system.

Can Chickens Eat Asparagus Leaves?

Yes, chickens can eat asparagus leaves and ferns. These leafy parts provide fiber, vitamins and phytonutrients.

Chop or roughly tear the leaves before feeding to make them easier for chickens to consume. This prevents whole leaves from being wasted.

Can Chickens Eat Asparagus Fern?

The fern-like foliage that grows after the asparagus spears can be fed to chickens. Ferns contain protein, minerals and bioactive compounds.

Remove any dried out or dead ferns and feed the fresh green leaves in moderation. Consider chopping them up for easier eating.

How to Feed Asparagus to Chickens

Follow these tips for safely feeding asparagus to chickens:

Avoid Feeding Tough Parts

Only feed the tender spears and leaves. Remove old stems or tough portions which are hard to digest.

Don’t Feed Asparagus to Baby Chicks

Wait until chicks are fully feathered at 6-8 weeks old before offering any asparagus to avoid digestive upset.

Introduce Slowly

When first offering asparagus, only feed a small amount to see how chickens tolerate it. Watch for signs of diarrhea.

Never Add Seasonings

Avoid flavored, salted or oiled asparagus. Feed plain, unseasoned spears to prevent toxicity.

Chop Into Bite-Sized Pieces

Cut spears into 1-2 inch pieces so chickens don’t waste any. The smaller size allows easier eating.

Provide in Moderation

Asparagus should only make up a small part of a chicken’s diet. Overfeeding can cause loose droppings.

Follow these best practices for safely incorporating asparagus into your chickens’ diet. Offer it as the occasional treat to take advantage of its nutrition.

How Much Asparagus Can Chickens Eat?

Chickens should only eat a moderate amount of asparagus. About 1-2 spears, 2-3 times per week is a good amount for each hen.

Overfeeding asparagus can irritate chickens’ digestive systems…

Overfeeding asparagus can irritate chickens’ digestive systems, causing diarrhea. Introduce it slowly and find the right amount your flock can tolerate.

The leafy parts, tops and stems that are removed when harvesting spears provide another way to feed asparagus more frequently. Small amounts given daily or every other day is fine.


Asparagus should never make up more than 10% of a chicken’s total diet. Feed other fruits, veggies and greens in rotation for variety.

Does Feeding Chickens Asparagus Change Egg Quality?

The nutrients in asparagus can lead to some improvements in egg quality when fed to laying hens:

  • Increased vitamin A leads to darker, richer egg yolks
  • Essential minerals result in stronger egg shells
  • Antioxidants protect freshness and prevent spoilage
  • Carotenoids may enhance yolk color slightly

These positive effects will be subtle though. Don’t expect dramatic changes in eggs from solely feeding asparagus. It works best as part of varied diet.

Can Baby Chickens Eat Asparagus?

It’s best to wait until chicks are fully feathered and 8 weeks old before feeding them any asparagus.

Their digestive systems are too immature to properly digest the fibrous texture. Stick to starter feed for the first 6-8 weeks.

Once juvenile chickens are 2 months of age, they can start being introduced to small pieces of tender asparagus spears and leaves. Avoid giving too much at once.

Asparagus supports growth and development as an occasional treat for maturing pullets and cockerels. Just feed in moderation due to its diuretic effects.


In conclusion, chickens can safely eat asparagus for its nutritious content of vitamins, minerals and antioxidants. Both the spears and leafy parts provide benefits.

Asparagus supports egg production, immune function, digestion and growth. However, proper preparation and portion control is important.

By following the feeding guidelines, you can incorporate asparagus as a healthy supplemental treat into your chicken’s diet a few times a week.
