Article Summary

  • Chickens can eat small amounts of flour, but it should not make up a significant part of their diet due to the lack of essential nutrients.
  • Flour is mostly starch, which chickens have difficulty digesting, and excessive consumption can lead to digestive issues.
  • Certain precautions should be taken, such as avoiding seasoned flours with added salt, spices, or sugar.

Flour is a pantry staple in most homes, but should you share it with your backyard chickens? Many chicken keepers have this question about incorporating flour into their flock’s diet.

While chickens can eat small amounts of flour, it should not make up a significant part of their food intake. Flour lacks important nutrients chickens need to stay healthy. However, occasional flour treats or using flour to administer medication is usually fine.

This article will explore the pros and cons of feeding flour to chickens. We’ll cover how it impacts their digestive system, which types are safest, and best practices for incorporating flour into their feed. Read on to get the full scoop on whether chickens can eat flour.

How Well Can Chickens Digest Flour?

Chickens have a fast digestion time, processing food in just 2-6 hours on average. This rapid transit time means their bodies are not well equipped to break down complex carbohydrates like flour.

Flour is mostly starch, which chickens cannot fully digest. Since chickens lack sufficient amylase enzymes in their saliva and pancreas, the starch passes through their system mostly intact. Eating too much can lead to blocked digestive tracts.

Chickens have gizzards to grind down food like grains, but flour is too finely milled for the gizzard…

While chickens have gizzards to grind down food like grains, flour is too finely milled for the gizzard to break it down further. Passing through undigested, the flour absorbs water and forms a glutinous mass. This can cause intestinal issues for chickens over time.

In small doses though, chickens can tolerate flour just fine. Whole grain flours like wheat and oat bran are easiest for chickens to digest. But all-purpose white flour provides empty calories and lacks nutritional benefits.

Benefits and Risks of Feeding Flour to Backyard Chickens

Occasionally feeding chickens flour as a treat poses little harm. In moderation, benefits include:

  • Extra calories for warmth in cold weather
  • Mix with medicine for picky eaters
  • Bonding time for you and your flock

However, routinely using flour in chicken feed carries some risks, including:

  • Nutritional deficiencies since flour lacks vitamins and minerals
  • Dehydration from water absorption in the gut
  • Pasted vent if high flour diet causes diarrhea
  • Impacted crop if flour compacted into a mass

Feeding flour should be an occasional treat, not an everyday occurrence. Limit flour treats to no more than once a week for a healthy diet. Monitor chickens closely afterward for any signs of digestive upset.

What Kinds of Flour Can Chickens Eat?

Chickens can eat most types of flour in moderation, but some choices are healthier than others. Here are some common flours that backyard chickens can consume:

Wheat Flour

Whole wheat flour offers more nutrition than white all-purpose flour. The bran provides fiber to aid digestion. However, only feed wheat flour sparingly since chickens cannot absorb all its nutrients.

Oat Flour

Made from ground oats, this light flour is high in protein and fiber. Its soft texture makes it one of the easiest for chickens to break down and digest.

Corn Flour

Corn flour adds carbohydrates for energy but lacks other nutrients. It contains more fat than other flours so may turn rancid quicker. Best to feed fresh and not leave out in hot weather.

Cassava Flour

This starchy flour made from yucca root is gluten-free. But it can be heavy and high in carbohydrates for chickens to digest efficiently.

Coconut Flour

While rich in fiber and protein, coconut flour sucks up moisture in the digestive tract. Limit intake to avoid dehydration.

Rice Flour

A fine textured flour, but the lack of nutrients does not make it a good dietary staple. Best avoided or used very sparingly.

Almond Flour

High in protein and healthy fats. Because it’s rich and dense, feed almond flour in moderation. Rancid flour can make chickens sick.


When exploring different flour options, keep nutritional content in mind. Avoid any seasoned flours with added salt, spices, or sugar. Stick to plain, whole grain varieties in small amounts.

Frequently Asked Questions About Feeding Chickens Flour

Chicken keepers tend to have some common questions around sharing flour with their flocks. Here are answers to some of the top queries.

Can Chickens Eat Flour Tortillas?

Yes, chickens can occasionally eat small pieces of plain flour tortillas as a treat. Just be sure to tear off small pieces – eating too much could lead to intestinal blockages. Corn tortillas are lower in starch and a healthier option.

Can Chickens Eat Bread Flour?

Bread flour is high in gluten to achieve an elastic dough texture. This can be harder for chickens to break down. White bread flour also lacks nutritional value. Occasional treats of whole wheat bread flour are safer.

Can Baby Chicks Eat Flour?

Baby chicks under 4 weeks old should not eat flour. Their developing digestive systems cannot handle the thickness and gluten. Instead, feed chick crumble which is nutritionally formulated for their growth needs.

Can Chickens Eat Masa Flour?

Masa harina corn flour can be fed to chickens in moderation. Soaked in water first, the soft dough texture makes it easier to digest. But the starch content means it should only be an occasional snack.

How Do You Feed Flour to Chickens?

The safest way to feed flour is mixed into a crumbly dough, not loose and powdery. Add just 1-2 tablespoons of flour per chicken and mix with water into a ball they can peck at. Scatter on the ground outside to avoid a mess.

Healthy Ways to Use Flour in Your Flock’s Diet

When used properly, flour can be a valuable tool in a chicken keeper’s arsenal. Here are some healthy ways to incorporate moderate amounts of flour:

  • Hide pills or nutrient powders in flour dough balls
  • Mix a small amount into scratch feed or oats
  • Make edible play dough with flour, water, and food coloring
  • Coat dandelion or kale leaves in flour to encourage foraging
  • Knead vitamins into a flour and water dough as a boredom buster

The key is using flour as an additive, not the main meal. Focus on well-balanced layer feed, produce scraps and insects as the bulk of their diet. A flour-based treat adds enriching variety like any occasional table food treats for chickens.


Flour won’t provide complete nutrition for chickens, but the occasional serving can be a safe treat. Stick to whole grain flours and limit intake to less than once a week.

Monitor chickens afterward and adjust quantities if any experience digestive distress. Focus on a diverse diet and supplement flour lightly for fun. With careful moderation, chickens can enjoy the benefits of flour safely.
