Walnuts can be a healthy and delicious treat for chickens in moderation. Here is a comprehensive guide on feeding walnuts to chickens safely.

Walnuts are a nutrient-dense food loaded with healthy fats, protein, fibers, and minerals like manganese and copper. This makes walnuts an excellent addition to your chicken’s diet. However, too many walnuts can cause health issues. So should chickens eat walnuts and if so, how much? Read on to find out.

Is It Safe for Chickens to Eat Walnuts?

Yes, chickens can safely eat walnuts in moderation. Walnuts offer many nutritional benefits for chickens. They are a good source of energy and healthy fats. They also contain antioxidants and omega-3 fatty acids that support chicken health.

However, walnuts do contain trace amounts of juglone, a compound that can be toxic to chickens if consumed in excess. As long as chickens are fed walnuts occasionally and in small quantities, juglone toxicity is very unlikely.

Health Benefits of Feeding Walnuts to Chickens

Here are some of the key benefits of adding walnuts to a chicken’s diet:

  • Walnuts are high in protein, providing amino acids for growth and maintenance.
  • They contain omega-3 fatty acids like ALA that support brain and eye health in chickens.
  • Walnuts offer antioxidants that boost immunity and overall health.
  • They provide insoluble fiber for healthy digestion.
  • Walnuts contain manganese, copper, phosphorus, and other minerals chickens need.
  • The healthy fats in walnuts promote radiant feathers and skin.
  • Walnuts may help chickens maintain a healthy weight.

Potential Risks of Overfeeding Walnuts to Chickens

While walnuts are safe for chickens in moderation, overdoing it can cause problems including:

Digestive issues: Too many walnuts could lead to loose droppings or diarrhea.

Juglone toxicity: Excess juglone from walnuts can damage chickens’ nervous systems and organs.

Obesity: The high-fat content of walnuts could cause weight gain if overfed.

Nutritional imbalance: Overfeeding treats like walnuts can displace more balanced feed.


To avoid these risks, walnuts should be limited to occasional small servings. Moderating walnut intake allows chickens to benefit without adverse effects.

What Type of Walnuts Can Chickens Eat?

Chickens can safely eat all common walnut varieties, including English/Persian walnuts, black walnuts, and white (butternut) walnuts. Each offers slightly different nutrient profiles, but all provide healthy fats, protein, minerals, and antioxidants.

English walnuts are the most widely available and make a great choice. But feel free to offer whatever walnut varieties you have on hand. Just be sure they are fresh and mold-free.

How Much Walnuts Can Chickens Eat?

Chickens should only eat walnuts in moderation, around 1-2 nuts per bird, 2-3 times per week. This limits juglone exposure while allowing chickens to benefit from walnuts’ nutrients and flavors.

For comparison, a one ounce serving of walnuts (about 14 halves) for humans is a reasonable portion. Scale this down for chickens based on their smaller size and feed no more than a couple of nut halves at a time.

It’s best to start slowly when introducing new treats. Observe your chickens after feeding walnuts to ensure none have adverse reactions.

How to Feed Walnuts to Chickens

Here are some tips for safely incorporating walnuts into your chickensโ€™ diet:

  • Chop walnuts into smaller pieces so they are easier for chickens to eat.
  • Mash or grind a few walnuts and mix them into feed for flavor.
  • Offer walnuts as a free choice snack in a separate dish.
  • Scatter whole or chopped walnuts in chicken runs as a fun foraging activity.
  • Mix finely chopped walnuts into homemade treat balls along with oats, seeds, etc.
  • Always provide plenty of fresh water when feeding drier treats like walnuts to help with digestion.

How Often Can Chickens Eat Walnuts?

Aim to feed chickens walnuts in moderation 2-3 times per week at most. Small daily treats are not recommended due to the juglone content.

Pay attention to your chickens’ droppings after feeding walnuts. Loose droppings may be a sign they need more time to digest and adjust to the fats and fibers.

Rotate walnuts with other healthy snacks like rolled oats, sunflower seeds, fruits, and veggies to add variety to their diet. This prevents boredom and overconsumption of any one treat.

Can Baby Chicks Eat Walnuts?

Walnuts are not recommended for baby chicks under 16 weeks old. Chicks require a specialized starter feed to support their rapid growth and development.

Once chicks mature into pullets around 16-18 weeks, you can start offering small nut pieces and other treats. But until then, it’s best to stick to chick starter feed and avoid snacks like walnuts.

In summary, walnuts are a nutritious supplement for mature chickens but babies should avoid them. Follow chick feed directions for the first 16 weeks, then gradually introduce treats.
