Sunflower seeds are a common treat for backyard chickens. But can chickens eat sunflower seeds safely? What are the benefits and potential risks? This article takes an in-depth look at feeding sunflower seeds to chickens.

Is Sunflower Seed Safe for Chickens?

The short answer is yes, sunflower seeds are safe and healthy for chickens to eat. In fact, sunflower seeds provide a number of key nutrients that are great for your flock.

Sunflower seeds are high in fat and protein, making them an excellent source of dietary energy. The fat content helps chickens put on weight and keep warm during cold months. The protein supports muscle growth and egg production.

Sunflower seeds also contain vitamins and minerals…

Sunflower seeds also contain vitamins and minerals like vitamin E, magnesium, phosphorus, zinc, iron and selenium. These micronutrients play a role in immune function, metabolism, feathering and more.

So not only are sunflower seeds safe for chickens to consume, they offer nutritional benefits. Moderation is still key, but sunflower seeds can be a regular treat.

What Makes Sunflower Seeds So Good for Chickens?

There are a few key reasons why sunflower seeds are so beneficial for backyard chickens:

High in healthy fats – The primary fat in sunflower seeds is linoleic acid, an omega-6 fatty acid important for skin and feather health. The high fat content helps meet chickens’ needs for dietary energy.

Excellent source of protein – Sunflower seeds provide well-balanced amino acids for building and maintaining muscle. Protein is particularly important for egg-laying hens.

Rich in vitamin E – Vitamin E supports a healthy immune system and is also a natural antioxidant. Sunflower seeds are one of the best sources of this vitamin.

Good source of B vitamins – Sunflower seeds provide B vitamins like niacin, folate and thiamine. These aid in metabolism and nervous system function.

High in zinc and selenium – Two minerals that play key roles in immunity, reproduction and thyroid hormone activity.


When fed in moderation, the nutritional profile of sunflower seeds makes them a smart choice for any backyard flock. The combination of protein, healthy fats and antioxidants is what makes them so beneficial.

Can Feeding Sunflower Seeds Harm Chickens?

While sunflower seeds are a safe, healthy treat, overdoing it on sunflower seeds could cause issues:

  • Too much fat – While the fat in sunflower seeds is largely the healthier kind, excessive intakes could contribute to obesity. Moderation is key.
  • Unbalanced diet – Sunflower seeds lack calcium and some other minerals chickens need. Relying too heavily on sunflower seeds could lead to deficiencies over time.
  • Reduced appetite – The high fat and protein content of sunflower seeds is very satisfying to chickens. Offering too many could lead to reduced consumption of a complete feed.
  • Digestive issues – Eating too many sunflower seeds could potentially upset the digestive system, causing loose stool or diarrhea. It’s best to introduce them gradually.

As long as you feed sunflower seeds in moderate amounts as part of a balanced diet, they are unlikely to cause harm. Never exceed more than 10% of the total diet as sunflower seeds.

Is Commercial Sunflower Seed As Good?

Commercial sunflower seeds sold for human consumption are fine for chickens to eat. However, there are a few disadvantages compared to raw, whole sunflower seeds:

  • Less fresh – Commercial sunflower seeds are often sourced months in advance so they lose some freshness. Raw sunflower seeds will be freshest.
  • Lack of shells – The shells provide an extra source of fiber and minerals. Shelled commercial seeds won’t have this benefit.
  • Salted varieties – Many roasted/salted sunflower seeds have added seasonings high in sodium. Purchase plain, unsalted varieties.
  • Oil separation – Bags of sunflower seeds sometimes have accumulated oil at the bottom. This oxidized oil could cause diarrhea.

Overall, commercial sunflower seed products are convenient but not quite as ideal as raw, whole sunflower seeds purchased from a local grower or feed store. Make sure to read labels and watch out for anything potentially harmful if buying commercial.

Can Chickens Eat Raw Sunflower Seeds?

Yes, chickens can safely eat raw sunflower seeds either whole or shelled. In fact, raw sunflower seeds are the most natural, healthy form for chickens.

Raw sunflower seeds retain all their original freshness and nutritional integrity. The vitamin E content in particular degrades rapidly with heat processing.

Whole raw sunflower seeds also provide an extra dose of fiber, healthy fats and minerals from the shell. The shell itself is soft and easily crushed by the chicken’s gizzard.

The only downside is that raw sunflower seeds are more prone to rancidity than roasted seeds. Make sure raw seeds look and smell fresh. Store any excess carefully in a sealed container in the fridge or freezer.

Overall, raw sunflower seeds are an excellent source of nutrition and safe for any backyard flock.

Can Chickens Eat Salted Sunflower Seeds?

It’s best to avoid giving chickens sunflower seeds with added salt, seasonings or flavorings. While a few won’t cause major issues, regularly feeding salted sunflower seeds could lead to health problems.

Chickens have a very limited ability to process excess sodium in their diet. Too much can lead to kidney damage, heart issues and poor growth.

Many seasoning mixes also contain garlic or onion powder, both of which are toxic to chickens. Even black pepper is not recommended.

…the flavors of seasoned sunflower seeds could discourage chickens from eating their normal feed…

Lastly, the flavors of seasoned sunflower seeds could discourage chickens from eating their normal feed, which would have negative effects long-term.


If you want to share some from your stash, rinse salted sunflower seeds well to remove some of the salt. But don’t make a regular habit of feeding seasoned sunflower seeds to your flock.

Can Chickens Eat Sunflower Seeds?

Yes! Sunflower seeds are safe, healthy and nutritious for chickens to eat. In moderation, they make a great supplemental treat.

Whole sunflower seeds provide an excellent combination of protein, fatty acids, antioxidants, vitamins and minerals. Many of these nutrients are beneficial for chicken health and egg production.

The shells add valuable fiber to help digestion and provide calcium. This makes whole raw sunflower seeds the best option.

Just be careful not to overdo it. Aim to feed less than 10% of the total diet as sunflower seeds. Free-choice is not recommended, as chickens will overeat all the tasty sunflower seeds.

Overall, sunflower seeds can absolutely be part of a balanced diet for backyard chickens when fed responsibly. The nutritional benefits far outweigh any potential downsides.

Can Chickens Eat Sunflower Seeds With Shells?

A Close-Up Shot of Sunflower Seeds

Feeding whole sunflower seeds with the shell on is perfectly safe and even beneficial for chickens. Sunflower seed shells provide two key advantages:

1. Added fiber – Sunflower seed shells provide insoluble fiber that helps maintain healthy digestion in chickens. The coarse texture acts as a gentle abrasive in the gizzard to grind up and process food.

2. Extra minerals – The hulls contain calcium and other trace minerals not found within the seed itself. This adds to the overall nutritional value.

Sunflower seed shells are soft, thin and easily crushed by a chicken when consumed whole. The shell does not need to be removed or broken.

In fact, shells add an important dimensionality to the diet. Many chickens enjoy the activity of breaking open whole sunflower seeds too.

The only downside is possible messiness around the coop. But overall, whole sunflower seeds with shells intact are great.

Can Chickens Eat Salted Sunflower Seeds?

It’s best to avoid feeding chickens sunflower seeds with added salt or seasonings. Salted sunflower seeds could cause these potential issues:

  • Excess sodium intake, which chickens have difficulty processing
  • Reduced appetite for regular feed and treats
  • Exposure to seasonings toxic to chickens like onion or garlic
  • Digestive upset from high salt or flavorings

If you want to share a few salted seeds, try rinsing them well first to remove some of the salt.

But avoid making salted sunflower seeds a regular treat. Plain, unseasoned is safest and healthiest for chickens. Too much sodium is hard on chickens’ kidneys and overall health.

Can Chickens Eat Roasted Sunflower Seeds?

While raw is best, chickens can safely eat roasted sunflower seeds in moderation. Light roasting at low temperatures preserves most of the micronutrient content.

However, extended high-heat roasting degrades the natural vitamin E found in sunflower seeds. Vitamin E is a valuable antioxidant for chicken health.

Also watch out for seasoned, flavored roasted varieties. Choose plain roasted sunflower seeds with zero additives.

Finally, roasted sunflower seeds lack the fiber benefits from the shells. So raw whole seeds are more well-rounded nutritionally.

Overall, light roasted sunflower seeds are fine for chickens as an occasional treat. But raw sunflower seeds will offer the biggest health gains. Try to pick unsalted, additive-free when buying roasted.

Can Chickens Eat Black Oil Sunflower Seeds?

Black oil sunflower seeds are perfectly healthy and safe for chicken consumption. They are simply a specific variety of sunflower favored for their high oil content.

The black oil comes from their thinner, smaller shells. This allows the inner kernel to be larger and contain more oil than other varieties.

In terms of nutrition, the profile is very similar to other sunflower seeds – high in protein, fatty acids, vitamin E and more. Their small size may mean chickens find them easier to eat.

Black oil sunflower seeds are readily available, affordable and make an excellent treat. They can be fed raw or roasted, whole or shelled. There are no downsides to choosing this high-oil variety for your flock.

How to Feed Sunflower Seeds to Chickens?

Here are some tips for safely incorporating sunflower seeds into your chickens’ diet:

  • Give as a treat – Sprinkle some over feed or offer free-choice in a small dish separate from regular feed.
  • Moderation is key – No more than 1-2 ounces per bird per day, and under 10% of total diet.
  • Offer raw whole seeds – Unroasted with shells provides the most nutrition and fiber.
  • Store properly – Refrigerate or freeze excess to prevent sunflower seeds going rancid.
  • Remove if uneaten – Don’t leave out in coop to avoid mold or rodents.
  • Avoid salted seeds – Purchase plain, unseasoned varieties only.
  • Gradually introduce – Start with small amounts and increase slowly to observe effects.

Following these tips will ensure sunflower seeds are a healthy supplemental feed rather than an unhealthy free-choice snack.

How Much Sunflower Seeds to Feed Chickens?

Sunflower seeds should make up no more than 10% of a chicken’s total daily diet. As a treat, aim for 1-2 ounces of sunflower seeds per chicken.

This equates to around 1/4 to 1/2 cup of sunflower seeds per bird per day. Adjust amounts based on your flock size and feed consumption patterns.

Free-feeding sunflower seeds often leads to overconsumption and obesity. It’s healthier to offer sunflower seeds in limited amounts 1-2 times daily.

Consider the following daily sunflower seed feeding guidelines:

  • Full-sized chickens: 1/4 cup
  • Bantam chickens: 2 tablespoons
  • Chicks under 12 weeks: 1 tablespoon or less

The high fat and protein content of sunflower seeds mean a little goes a long way nutritionally. Moderation is key for maintaining balanced nutrition.

What Age Can Chickens Eat Sunflower Seeds?

Chicks can start enjoying small amounts of sunflower seeds as early as 4-6 weeks old. By this age, their digestive system has matured enough to handle high fat feeds.

Initially offer just a few seeds at a time – a pinch for younger chicks and a tablespoon for chicks over 8 weeks old. Gradually increase the amount as they grow.

Wait until 12-16 weeks to offer sunflower seeds…

Wait until 12-16 weeks to offer sunflower seeds free-choice in a small dish. But still limit total quantities to avoid overconsumption of fat and calories.

Once chicks are fully feathered and on adult rations, around 16-20 weeks, you can treat them like adult chickens in terms of sunflower seed intake.


Pay attention to any digestive upset when introducing sunflower seeds to chicks. Decrease amounts or hold off if stool becomes loose after eating them.

Can Baby Chickens Eat Sunflower Seeds?

Baby chickens under 4 weeks old should not eat sunflower seeds, as their digestive system is too immature. Wait until 4-6 weeks of age before offering small portions.

Chick digesta relies on proteins from their starter feed ration for the first month after hatching. Their gut must develop further before it can properly digest fats.

The high fat content of sunflower seeds could lead to intestinal upset, diarrhea or impaired nutrition. Hold off until chicks are fully feathered and eating grower ration.

At 4-6 weeks, a few raw sunflower seeds can be offered as a treat. Limit treats to a tablespoon or less per chick at first. Gradually increase amounts as they mature.

Exercising patience and waiting until chicks are developmentally ready for sunflower seeds ensures their long-term digestive health and growth. With monitoring, even baby chickens can benefit from this nutritious treat.
