Spinach is a leafy green vegetable that is chock-full of vitamins, minerals, and nutrients that can offer tremendous benefits for chickens. However, moderation is key when feeding spinach to chickens. Here is a comprehensive guide on whether chickens can eat spinach and how to feed it to them safely.

Can You Feed Chickens Spinach?

Yes, chickens can eat spinach in moderation. Spinach contains calcium, vitamin K, vitamin A, folate, magnesium, iron, vitamin C, vitamin B2, potassium, and manganese. These nutrients help build stronger bones, aid in egg production, and support immune health in chickens.

However, spinach also contains oxalic acid which can bind to calcium and prevent absorption. Too much oxalic acid can lead to nutritional deficiencies. So feed spinach as an occasional treat, not a regular part of their diet.

Can Chickens Eat Spinach Raw or Cooked?

Chickens can eat both raw and cooked spinach. Cooking spinach helps neutralize some of the oxalic acid content. However, some nutrients like vitamin C and B vitamins are lost when cooking.

Lightly cooking or blanching spinach can make it easier for chickens to digest…

Lightly cooking or blanching spinach can make it easier for chickens to digest while retaining more nutrients. But raw, fresh spinach also offers benefits. The best approach is to feed chickens a combination of both raw and cooked spinach in moderation.

Can Chickens Eat Frozen Spinach?

Frozen spinach retains more nutrients than canned varieties. It’s perfectly safe for chickens to eat frozen spinach either thawed or partially thawed.

Make sure the spinach is completely thawed before feeding to avoid crop impactions. Mixing partially thawed spinach into their feed allows the spinach to thaw slowly in their digestive system.

Can Chickens Eat Fresh Spinach?

Fresh spinach right from the garden is a nutritious treat for backyard chickens. It provides more vitamins, minerals, and antioxidants compared to frozen or cooked spinach.


Introduce fresh spinach gradually to avoid digestive upset. Chop the spinach into small pieces for easier eating and serving it alongside their regular feed is best. Feed just a handful per chicken 2-3 times a week.

Is Spinach Good for Chickens to Eat?

Yes, spinach is a nutritious addition to a chicken’s diet in moderation. The vitamin K in spinach is essential for blood clotting and bone health. The carotenoids help with egg yolk pigmentation. And the antioxidants support immunity.

Just feed spinach as a supplemental treat, not an everyday vegetable, due to the oxalic acid content. Variety is important, so rotate spinach with other leafy greens like kale, Swiss chard, cabbage, and lettuce.

Health Benefits of Spinach for Chickens

Here are some of the top health benefits of feeding chickens spinach:

  • Stronger bones and eggshells from calcium, vitamin K, and manganese.
  • Carotenoids like lutein and zeaxanthin for egg yolk color.
  • Vitamin A for immune health and vision.
  • Vitamin C, E, and antioxidants to fight disease.
  • Iron for oxygen transport and energy.
  • Folate and B vitamins for metabolic function and growth.

Can I Give My Chickens Raw Spinach?

Yes, you can give chickens raw spinach in moderation. Introduce it slowly at first to see how their digestive system handles it. Chop the spinach into small pieces so it’s easier to eat.

Feed just a handful 1-2 times per week along with their feed to limit their oxalic acid intake. Offer a mix of raw and cooked spinach for the most benefits. Monitor for loose droppings as too much raw spinach can cause diarrhea.

Which Parts of Spinach Can Chickens Eat?

Chickens can eat all parts of spinach, including:

  • Spinach leaves – Contains the most nutrients. Chop into bite-sized pieces.
  • Spinach stems – Provides fiber. Can also be chopped small.
  • Spinach seeds – High in protein, fiber and omega-3s. Can aid digestion.


Avoid feeding the spinach roots or crowns as they are tougher to digest. The leaves, stems, and seeds offer the best nutritional value for chickens.

Can Chickens Eat Too Much Spinach?

Yes, chickens can experience adverse effects from eating too much spinach. These include:

  • Diarrhea, digestive upset from excess oxalic acid.
  • Nutritional deficiencies if oxalic acid binds too much calcium.
  • Reduced appetite if filling up on spinach rather than feed.
  • Green egg yolks from eating too many leafy greens.

To avoid these issues, feed spinach in moderation 2-3 times per week and not daily. Never exceed one cup per chicken per serving. Mix with their feed and other veggies for balanced nutrition.

Preparing Spinach for Your Flock

Here are some tips for preparing spinach to feed your flock:

  • Remove any wilted or slimy leaves.
  • Wash thoroughly to remove dirt and contaminants.
  • Chop leaves and stems into small, bite-sized pieces.
  • Lightly steam, blanch or sauté to reduce oxalic acid (optional).
  • Mix in with feed or offer spinach after chickens eat their regular meals.
  • Refrigerate any uneaten spinach promptly.

Introduce slowly and monitor chickens for any diarrhea or drop in feed intake. This will allow you to adjust spinach amounts appropriately.

In summary, chickens can enjoy spinach in moderation along with a balanced diet. Follow these guidelines for safely feeding spinach to your flock. The nutritional benefits far outweigh the risks when fed properly.

Frequently Asked Questions

Can chickens eat too much spinach?

Yes, chickens can eat spinach, but moderation is crucial. While spinach is a nutritious leafy green, it contains oxalic acid, which can hinder calcium absorption. Feeding chickens excessive amounts of spinach may lead to calcium deficiencies over time. It’s important to offer a well-balanced diet with a variety of foods to ensure their nutritional needs are met.

What greens should chickens not eat?

Chickens should avoid certain greens in excess due to potential health issues. Vegetables high in oxalic acid, such as spinach and Swiss chard, can interfere with calcium absorption. Additionally, toxic plants like those from the nightshade family (e.g., tomatoes, potatoes, and eggplant) and rhubarb leaves should be avoided, as they contain substances harmful to chickens.

Can chickens eat spinach and kale?

Yes, chickens can eat spinach and kale in moderation. Both are nutritious leafy greens that provide vitamins and minerals. However, because spinach contains oxalic acid, it’s important not to feed too much to prevent calcium absorption issues. Providing a mix of various greens ensures a more balanced and healthy diet for your chickens.

Can chickens eat bolted spinach?

Yes, chickens can eat bolted spinach. Bolted spinach refers to spinach that has started flowering. While bolted spinach may not be as tender as young leaves, it is still safe for chickens to consume. In fact, chickens often enjoy foraging on plants in various stages of growth.

What vegetables do chickens like the most?

Chickens tend to enjoy a variety of vegetables, but preferences can vary among individuals. Generally, they show enthusiasm for leafy greens like lettuce, kale, and Swiss chard. Additionally, many chickens like broccoli, cauliflower, and cabbage. Sweet and crunchy options like bell peppers and cucumbers are often well-received. Experimenting with different vegetables and observing your chickens’ reactions can help determine their favorite treats.
