Can Chickens Eat Dairy? What You Need to Know

Milk and Cheese at Picnic Time

Article Summary

  • Chickens are omnivores that can eat certain types of dairy as part of their diet; dairy, including cheese and yogurt, can provide protein, fat, calcium, and phosphorus for chickens.
  • When feeding dairy to chickens, it’s important to introduce new foods slowly, provide small amounts, and ensure the products are fresh.
  • Newly hatched chicks should not be given dairy until they are at least one month old, except for small amounts of yogurt with live active cultures.

Chickens are omnivores that can eat a wide variety of foods, including certain dairy products. Dairy can provide protein and fat to supplement a chicken’s diet. However, not all types of dairy are safe or healthy for chickens.

Is Dairy Bad for Chickens?

Dairy is not inherently bad for chickens. In fact, small amounts of certain dairy products can be a nutritious treat. Dairy provides protein, fat, calcium, and phosphorus – all nutrients chickens need.

However, chickens’ digestive systems are not designed to handle large amounts of dairy. Too much can lead to digestive upset, diarrhea, or other health issues.

Additionally, dairy has less nutritional value for chickens than their natural foods like insects, seeds, and plants. While the occasional dairy treat is fine, it should not make up a substantial part of a chicken’s diet.

Can Chickens Digest Dairy?

Like other foods chickens can eat, they can digest some types of dairy but not others. Here’s a breakdown:

Cheese: Yes, chickens can digest cheese in small amounts as an occasional treat. The fermentation process makes the lactose in cheese more digestible.

Yogurt: The live active cultures in yogurt aid chickens’ digestion of the milk proteins and lactose. Plain yogurt in moderation is fine.

Milk: Chickens struggle to digest the lactose in milk. Only small amounts of milk should be fed.

Butter: The fat and milk solids in butter are difficult for chickens to digest. Better to avoid giving them butter.

Ice Cream: The high sugar and fat content make ice cream hard for chickens to digest. Best not to give them ice cream.


Chickens can digest some dairy products, but other dairies are too high in lactose and fat for their digestive systems; remember, moderation is key.

Can Chickens Eat Dairy Powder?

Non-fat dried milk powder can be a good dairy option for chickens. The drying process breaks down the lactose, making it easier to digest. Milk powder can be fed dry or reconstituted with water.

Other dairy powders like buttermilk powder or whey powder are also fine for chickens. Just be sure to feed them in moderation. Too much dried dairy can lead to loose droppings.

Can Chickens Eat Butter?

It’s best not to feed chickens butter. The high fat content is difficult for chickens to digest. Eating butter can cause diarrhea, digestive upset, or even intestinal irritation.

Small pieces of butter once in awhile will not harm chickens, but butter should not be a regular part of their diet. There are healthier treats that provide protein and fat without the digestive issues.

How to Feed Dairy Products to Chickens

When feeding dairy to chickens, follow these tips:

  • Introduce new dairy foods slowly to allow chickens’ digestive systems to adjust
  • Provide only small amounts – dairy should be an occasional treat, not a dietary staple
  • Mix yogurt or cheese in with chickens’ regular feed
  • Offer milk powder dry or reconstituted with water
  • Make sure dairy products are fresh – do not feed moldy or spoiled dairy
  • Remove any uneaten dairy after 20-30 minutes

Feeding dairy this way will help prevent digestive upset in your flock. Monitor droppings when introducing new dairy products. Loose stools can be a sign a dairy food isn’t agreeing with them.

How Often Can You Give Chickens Dairy Products?

Chickens should only receive small amounts of dairy a couple times per week at most. Here are some guidelines on frequency:

  • Cheese: 1-2 times per week
  • Yogurt: 2-3 times per week
  • Milk: No more than once per week
  • Butter: Avoid completely or only on very rare occasions
  • Ice Cream: Avoid giving chickens ice cream

More frequent dairy treats can disrupt the balance of nutrients chickens need from their regular feed. Dairy should be an infrequent surprise, not a staple food source.

If you want to give your chickens more protein, consider mealworms, boiled eggs, peas, or cooked meat instead of large amounts of dairy.

Avoid Feeding Chickens Spoiled or Moldy Dairy

It’s important never to feed chickens dairy products that are past their prime. Moldy, sour, or spoiled dairy can make chickens very sick.

Signs dairy has gone bad include:

  • Mold on cheese or yogurt
  • Slimy or ropey texture
  • Sour smell
  • Expired sell-by or use-by date

Discard any iffy dairy rather than risk feeding it to your chickens. The bacteria from spoiled dairy and mycotoxins due to molds can be very harmful.

Stick to fresh dairy within its expiration date whenever you give your flock a dairy treat. Make sure to promptly remove any leftovers so it doesn’t have a chance to spoil in their coop.

Can Baby Chicks Have Dairy?

Dairy is not recommended for newly hatched chicks under 4 weeks old. Their digestive systems are too immature to handle dairy products.

Small amounts of yogurt with live active cultures can be beneficial…

Small amounts of yogurt with live active cultures can be beneficial to help chicks establish healthy gut bacteria. But otherwise, avoid feeding chicks milk, cheese, butter, or other dairy until they are fully feathered and at least one month old.

Chicks get the nutrients they need from a high-protein starter feed and chick grit. Dairy is not necessary at this young age. Wait until they mature to begin offering dairy in moderation.

Clean Up Leftovers after Feeding Your Chickens Dairy

Whenever you feed your flock dairy treats, be sure to clean up any leftovers within 30 minutes. Dairy left sitting in the coop can spoil quickly, attract pests, and pose a disease risk.

Here are some tips for cleaning up after dairy feeding:

  • Feed dairy in a confined area, not scattered in bedding
  • Only offer as much as chickens will eat in one sitting
  • Remove and discard any leftovers right away
  • Clean the area with a scrub brush, vinegar, and water
  • Don’t allow chickens access to dirty feed areas

Following this cleanup routine will keep your coop hygienic and prevent health issues. It takes discipline, but is worth it to safely enjoy feeding your chickens the occasional dairy delight.

Can Chickens Eat Cheese?

In moderation, chickens can eat most types of cheese as an occasional treat. Cheddar, Swiss, feta, and Monterey Jack are all fine options. Just introduce new cheeses gradually to see if they agree with your chickens’ digestion.

Avoid soft cheeses like brie and blue cheeses – these are too high in moisture for chickens. Also do not feed chickens processed cheeses with preservatives, as these additives can be harmful.

To feed cheese, dice it into small pieces and mix in with their feed. Remove any uneaten bits within 30 minutes. An ounce or two a couple times a week is a healthy cheese treat.

Can Chickens Eat Yogurt?

Plain yogurt can be a nutritious dairy treat for chickens thanks to its live cultures that support digestive health. Look for yogurt with no added sugars.

Two to three times a week, chickens can enjoy 1-2 tablespoons of yogurt per bird mixed into their feed. The probiotics in yogurt provide vitamins and promote good gut bacteria.

Do not give chickens yogurt past its expiration date or any moldy yogurt. Only offer fresh, plain yogurt in moderation.

Can Chickens Drink Milk?

Chickens can drink milk, but only in very small quantities. Milk contains lactose, which chickens struggle to digest. Too much can lead to diarrhea.

For a treat, add a teaspoon of milk to the chicken’s water once weekly. Make sure it is fresh whole milk, not spoiled or sour. After an hour or two, empty and refresh the water with plain clean water.

Avoid giving chickens free access to milk for drinking. The lactose overload can disrupt their digestive health. Use milk as an occasional treat, not a significant food source.

Can Chickens Eat Ice Cream?

It’s best not to feed chickens ice cream. The high sugar content can upset their digestive systems, and chickens struggle to metabolize the fat and milk ingredients.

A tiny bite of ice cream here and there won’t harm chickens, but it shouldn’t become a habit. The nutritional value is minimal compared to healthier treat options.

For a cooler summertime chicken treat, freeze yogurt, watermelon, or pineapple chunks instead of offering ice cream. Or stick to room-temperature dairy options for the rest of the year.

Frequently Asked Questions

Can my chickens eat dairy powder?

Yes, chickens can eat dairy powder in moderation. However, it’s essential to introduce it gradually to ensure they tolerate it well. Dairy powder can be a good source of calcium and protein for chickens, contributing to overall nutritional balance. Monitor your chickens for any adverse reactions and consult a vet if you have concerns.

Can chickens eat dairy eggs?

Chickens should not eat dairy eggs, as eggs laid by chickens are not considered dairy. Chickens are not mammals, and their eggs are produced through a different biological process. Feeding chickens their own eggs can lead to egg-eating behavior, a habit you’d want to avoid. Provide a well-balanced diet with proper nutrients to keep your chickens healthy.

Why can’t chickens eat dairy?

Chickens lack the necessary enzymes to digest lactose found in dairy products properly. Feeding chickens dairy can lead to digestive issues, including diarrhea and discomfort. While small amounts of dairy may be tolerated by some chickens, it’s generally advisable to avoid incorporating dairy into their diet. Opt for nutritionally balanced feeds and treats specifically formulated for poultry to ensure their well-being.
