So, What Exactly is a Leek?

Before exploring whether chickens can eat them, let’s first understand what leeks are. Leeks are a vegetable in the onion family, closely related to onions, garlic, scallions, and shallots. The edible part of the leek is a bundle of leaf sheaths that form a cylindrical stalk.

Leeks have dark green tops that transition to a pale green, then whitish base. They have a mild, sweet, onion-like flavor. Leeks are larger in size than scallions but smaller than onions. They are a popular vegetable used in many cuisines around the world.

Can You Safely Feed Leeks to Chickens?

Leeks are not toxic to chickens…

Now that we know what leeks are, let’s look at whether it’s safe for chickens to eat them. The good news is that yes, chickens can safely eat leeks in moderation as part of a balanced diet.

Leeks are not toxic to chickens. The main safety concern would be choking if you gave a whole leek to a chicken. So it’s best to chop leeks into small pieces before feeding to your flock.

It’s also a smart idea to introduce leeks slowly at first to watch for any signs of digestive upset. But overall, leeks don’t pose any serious risks and can be a healthy treat.

What Nutritional Benefits Do Leeks Offer?

Feeding leeks to chickens provides some excellent nutritional benefits. Here’s an overview of the key nutrients leeks can provide:

  • Vitamin A – Leeks contain carotenoid antioxidants like beta carotene which chickens convert to vitamin A. This vitamin supports immune health and egg production.
  • Vitamin K – Leeks are a great source of vitamin K which aids blood clotting and bone health in chickens.
  • Vitamin C – Leeks provide vitamin C which acts as an antioxidant and promotes immunity.
  • Iron – Leeks contain iron to support blood health and prevent anemia in your flock.
  • Manganese – This mineral in leeks helps form bone and eggshells and metabolizes carbohydrates and cholesterol.
  • Fiber – The fiber in leeks promotes good digestion and gut health.

So in short, leeks are packed with key vitamins, minerals, and fiber chickens need to stay healthy and productive!

What Parts of Leeks Can Chickens Eat?

Chickens can eat all parts of a leek, including the white base, light green stalk, and dark green leaves. Each part offers slightly different nutritional perks:

  • White leek base – This part is high in vitamin C and fiber.
  • Light green leek stalks – The stalks contain vitamins A, K, and C along with manganese.
  • Dark green leaves – The leaves provide iron, calcium, carotenoids, and folate.

So feel free to feed your chickens leeks from root to stem! Just chop the leeks, especially the tough green tops, into bite-sized pieces for easy eating.

Should You Feed Raw or Cooked Leeks?

Chickens can eat leeks raw or cooked. Both forms provide benefits:

  • Raw – Raw leeks retain more vitamin C and digestive enzymes. The crunch of raw leeks can aid dental health.
  • Cooked – Lightly cooking leeks breaks down fiber for easier digestion and makes vitamins like A more bioavailable.


For the best of both worlds, try offering your flock a combo of raw and cooked leeks. Lightly steam, saute or blanch leeks to soften them while retaining some crunch and nutrients.

How Much Leeks Can Chickens Eat?

When adding any new treat to your chickens’ diet, start with moderation. Offer just a small portion at first to see how your flock responds. If their digestion seems fine, you can increase the amount.

As a general rule, leeks should make up no more than 5-10% of your chickens’ overall daily food intake. For a standard-sized leek, you can feed each chicken around 1-2 tablespoons (15-30g) per day. Adjust amounts based on the size of your chickens and their appetite.


To encourage foraging, chop leeks into pieces and scatter them in their run. You can also mix chopped leeks into their feed or offer leeks free-choice in a separate feeding station.

Are Leeks Suitable for Baby Chicks Too?

Baby chicks can also eat leeks in moderation. The vitamins, minerals, and antioxidants support their rapid growth and development. Here are some tips for feeding leeks to chicks under 12 weeks old:

  • Chop leeks extra fine into tiny pieces to prevent choking.
  • Start with just a pinch of leeks once or twice a week.
  • Slowly increase to 1-2 times daily as chicks grow.
  • Mix leeks into a crumble ration or moist mash for easiest eating.
  • Avoid feeding raw leeks; cook lightly to aid digestion for young chicks.

As chicks mature, transition them slowly to the recommended serving size for adult chickens.

Potential Downsides to Feeding Leeks

Leeks make a nutritious supplement for chickens but a few downsides are worth noting:

  • Leeks can cause loose droppings if fed in excess. Start slowly.
  • Leeks have a high water content which can dilute nutritional intake if fed in large amounts.
  • The onion family can cause hemolytic anemia in pets but this is very rare in chickens.
  • Leeks grow in contact with soil which may harbor parasites or heavy metals to avoid.

As long as you feed leeks in moderation as part of a varied diet, they make an excellent nutritional addition for your flock!

Feeding Leeks to Chickens: Final Tips

Leeks can be a healthy, safe, and nutritious treat for chickens. Here are some final tips on feeding leeks:

  • Always chop leeks to prevent choking and aid digestion
  • Introduce leeks slowly then increase portion size gradually
  • Combine raw and cooked leeks for optimal nutrition
  • Target 5-10% of daily intake from leeks, adjust as needed
  • Supervise chicks under 12 weeks and feed tiny pieces

Can chickens eat leeks seeds?

Yes, chickens can safely eat both leek seeds and the green leaves of leeks. Leeks are part of the allium family, along with onions and garlic, and contain compounds that can be beneficial for chicken health.

Can chickens eat leeks raw or cooked?

Chickens can eat leeks both raw and cooked. Raw leeks provide more active enzymes and nutrients, while cooking leeks can make them easier to digest.

For variety, offer chickens both raw and cooked leeks in moderation.

How much leeks to feed chicken?

Feed chickens leeks in moderation as part of a balanced diet. For a flock of 4-5 chickens, aim to feed around 1-2 leeks 2-3 times per week. Chop leeks into small pieces so chickens do not choke. Introduce leeks slowly at first to monitor for any digestive issues. Overfeeding leeks can lead to loose droppings, so adjust amounts based on the chicken’s reaction. Moderation is key when feeding leeks to chickens.
