Quick Answer:- Can Chickens Eat Mushrooms?

Yes, chickens can eat mushrooms. It’s worth noting that these feathered creatures are omnivorous, meaning they consume a mixture of plant and animal materials. Mushrooms, being fungi, fall within their dietary range. However, like with any other food, mushrooms should be fed to chickens in moderation. It’s crucial to ensure that the mushrooms are not toxic varieties, as some wild mushrooms can be harmful or even fatal to chickens.

Whilst mushrooms can be a part of a chicken’s diet, it’s worth remembering to offer them a varied and balanced diet. As part of a diverse diet, you might consider feeding chickens blueberries as well, which can be a healthy and enjoyable treat for them. However, always remember to feed any treats or non-traditional foods in moderation.

Are Mushrooms Harmful To Chickens?

While most common, store-bought varieties of mushrooms are perfectly safe for chickens, there is a risk when it comes to wild or certain toxic varieties. Just as some types of wild mushrooms are poisonous to humans, the same applies to chickens.

Examples of toxic mushrooms include the Death Cap, Destroying Angels, and the Deadly Webcap. These and other poisonous types contain harmful toxins that can cause serious health issues in chickens, and can potentially be fatal. It’s important to remember that chickens can’t distinguish between safe and toxic mushrooms, so it’s up to their caretakers to ensure they aren’t exposed to potentially harmful fungi.

If you or your neighbours have mushrooms growing in your gardens, it’s worth identifying them before allowing your chickens to peck around freely. If in doubt, removing the mushrooms or restricting access to them is a wise precaution.

In conclusion, while mushrooms aren’t inherently harmful to chickens, their safety depends on the specific variety of mushroom. Always err on the side of caution and stick to feeding chickens store-bought mushrooms or other known safe foodstuffs.

Are There Any Risks Of Feeding Mushrooms To Chickens?

While we’ve established that not all mushrooms pose a threat to chickens, feeding them this type of fungi is not without potential risks. The dangers mainly emerge from the possibility of chickens consuming toxic types or ingesting mushrooms in excessive amounts. Let’s delve into some of the risks linked with feeding mushrooms to chickens.

Ingestion of Toxic Varieties: The most significant risk lies in chickens consuming poisonous types of mushrooms. Some mushrooms, especially certain wild varieties, contain harmful toxins that can cause serious health issues, including organ failure and potentially death.

Overconsumption: Like with any other treat, feeding chickens mushrooms in excess can lead to dietary imbalance. A healthy chicken diet should be primarily composed of a complete commercial feed, and mushrooms should only be an occasional treat.

Reduced Nutrient Absorption: Some mushrooms can inhibit the absorption of nutrients in the chicken’s gut. This can lead to nutrient deficiencies if mushrooms make up a significant portion of their diet.

Digestive Problems: Mushrooms are high in fibre, and while a certain amount of fibre is good for chickens, too much can cause digestive issues like diarrhoea.

Allergic Reactions: Although it’s rare, chickens, like humans, can have allergic reactions to certain foods. If a chicken is allergic to mushrooms, it could experience adverse symptoms.

Potential for Fungal Overgrowth: Consuming large amounts of fungi might increase the risk of fungal overgrowth in the chicken’s gut, leading to potential health complications.

Mycotoxin Contamination: Some mushrooms can become contaminated with mycotoxins (fungus-produced toxins), which can cause a variety of health problems.

Pesticide Exposure: Store-bought mushrooms may have been treated with pesticides or other chemicals, which could pose a risk if not thoroughly washed before feeding.

Choking Hazard: Although it’s a risk with any food, larger pieces of mushrooms can present a choking hazard to chickens, especially younger ones.

Potential for Food Poisoning: If mushrooms are spoiled or not stored properly before feeding, they could cause food poisoning.

In summary, whilst mushrooms can be a novel addition to a chicken’s diet, they carry potential risks that require careful management. The dangers range from consumption of toxic varieties, overconsumption, to possible allergic reactions and more. Therefore, it’s vital to feed chickens mushrooms cautiously and always in moderation, alongside a well-balanced diet that meets their nutritional needs. Remember, when it comes to feeding chickens, safety should always be a priority.

Are Mushrooms A Good Source Of Nutrition For Chickens?

Despite the potential risks we’ve outlined, mushrooms, when safely sourced and served in moderation, can provide nutritional benefits to chickens. Mushrooms are packed with several essential nutrients that can contribute positively to a chicken’s overall health and wellbeing. Let’s explore these nutrients and their respective benefits in the table below:

NutrientNutritional Benefit
ProteinProteins are vital for growth, egg production, feather formation, and general health.
FibreThis aids in the proper functioning of the digestive system, helping chickens process their food more efficiently.
PotassiumIt supports heart health, enhances muscle function, and contributes to maintaining a fluid balance in the body.
Vitamin BB vitamins support metabolism, nervous system function, and overall growth and development.
Vitamin DThis vitamin is critical for calcium absorption, which is crucial for bone health and eggshell formation.
SeleniumIt’s an essential antioxidant that aids in supporting the immune system and reproductive health.

It’s worth reiterating that while mushrooms can be beneficial, they should be served as a supplement to a balanced chicken diet, not a staple. A healthy chicken diet consists mainly of a complete poultry feed with occasional treats like fruits, vegetables, and other safe food items. For instance, consider feeding chickens watermelon, which offers its own array of nutritional benefits. As always, moderation and variety are key to maintaining the health of your flock.

Types of Mushrooms For Chickens

When it comes to feeding chickens mushrooms, it’s important to stick with varieties that are safe and non-toxic. Here are some types of mushrooms that are commonly found in the UK, which can be safely fed to your chickens:

Button Mushrooms: Also known as white mushrooms, these are the most common variety found in supermarkets. They are completely safe for chickens and can be fed either raw or cooked.

Chestnut Mushrooms: These have a slightly stronger flavour than button mushrooms and are also safe for chickens to consume. They are a popular choice in the UK and can be readily found in most grocery stores.

Portobello Mushrooms: Essentially matured button mushrooms, Portobellos have a robust, meaty texture. They are non-toxic to chickens and can serve as a substantial treat.

Cremini Mushrooms: Sometimes referred to as ‘baby bellas’, these are a bit more flavourful than button mushrooms but still safe for chickens.

Oyster Mushrooms: These are safe for chickens and are easily identifiable with their fan-like shape. They are often cultivated at home, which makes them a convenient choice for many.

Shiitake Mushrooms: Commonly used in cooking, shiitake mushrooms are safe for chickens. However, they are usually more expensive than other varieties, so they may not be the most cost-effective option for chicken treats.

Remember, any mushroom given to chickens should be fresh and in good condition. Spoiled mushrooms can harbour bacteria and mould, which could lead to health issues. Also, store-bought mushrooms should be thoroughly washed to remove any potential pesticide residue. Lastly, if you’re not completely sure if a type of mushroom is safe for chickens, it’s best to avoid it. When in doubt, prioritise your chickens’ health and safety.

Do Chickens Like Mushrooms?

Chickens have individual tastes, much like humans, so their fondness for mushrooms can vary. Some chickens may enjoy the texture and flavour of mushrooms, while others may be indifferent or even avoid them altogether.

It’s worth noting that chickens tend to be more attracted to brightly coloured foods, which may explain why some might be less interested in mushrooms due to their more subdued colours. Nonetheless, many chicken keepers have found that their chickens will eat and enjoy mushrooms, especially when they’re chopped into smaller, manageable pieces.

If you’re introducing mushrooms to your chickens for the first time, it’s a good idea to start with small amounts to see how they react. If your chickens are not interested in the mushrooms, there’s no need to insist. There are plenty of other treat options out there, such as fruits and vegetables, which your chickens might find more appealing. Remember, the key is to provide a varied and balanced diet to ensure your chickens get all the nutrients they need.

Can Chickens Eat The Stems Of Mushrooms?

Yes, chickens can eat both the caps and the stems of mushrooms. There’s no significant difference in the nutritional content between these two parts, and both are safe for chickens to consume. However, it’s important to chop the stems into smaller, manageable pieces to prevent any potential choking hazards, especially when dealing with larger, thicker stems.

Also, it’s worth noting that while chickens can eat mushroom stems, these should still be non-toxic, store-bought, or identified safe wild varieties. Regardless of the part of the mushroom, the risk of toxicity in certain types still applies.

As with any other treat, always feed mushrooms, including their stems, in moderation, and as part of a balanced diet. It’s crucial not to let treats, no matter how healthy, displace the core nutrition your chickens receive from a high-quality poultry feed.

How Should You Serve Them Mushrooms?

When serving mushrooms to chickens, there are a few best practices to keep in mind to ensure their safety and enjoyment:

Buy From Trusted Sources: Make sure to get your mushrooms from a reliable source to avoid potential exposure to toxic varieties. Supermarkets and trusted local grocers are ideal.

Wash Thoroughly: Before serving, wash the mushrooms thoroughly under running water to remove any possible chemical residue or dirt.

Chop Into Small Pieces: To prevent any risk of choking, especially for younger birds, chop the mushrooms into small, manageable pieces.

Serve Raw or Cooked: You can serve mushrooms to chickens either raw or cooked. However, avoid using any seasonings or oils if you decide to cook them, as these can be harmful to chickens.

Watch for Leftovers: Remove any uneaten mushrooms after a few hours to prevent them from spoiling, as rotten mushrooms can lead to health issues.

Monitor Their Reaction: Watch your chickens as they eat the mushrooms. If they seem to enjoy them, you can continue to offer mushrooms as a treat occasionally. If they ignore the mushrooms, try other safe fruits and vegetables instead.

Remember, while mushrooms can be a nice addition to your chickens’ diet, they should never replace a complete poultry feed, which provides all the essential nutrients your chickens need to thrive. As always, treats should only constitute a small portion of their overall diet.

How Much Mushrooms Can Chickens Eat?

As with any treat you give to your chickens, moderation is key when feeding them mushrooms. Although mushrooms are non-toxic (assuming they’re safe varieties) and can provide certain nutritional benefits, they should not constitute a large part of your chickens’ diet.

A good rule of thumb to follow is the “90/10 rule”. This guideline suggests that 90% of your chickens’ diet should consist of a complete, balanced poultry feed, and the remaining 10% can be made up of treats like fruits, vegetables, and in this case, mushrooms. This balance ensures your chickens get all the necessary nutrients they need to stay healthy, produce eggs, and grow feathers.

The exact quantity can vary depending on the size and breed of your chickens. A small handful per chicken, once or twice a week, would typically be considered a moderate amount. As always, it’s important to observe your chickens after introducing any new food into their diet. If you notice any adverse reactions or changes in behaviour, stop feeding them the mushrooms and consult with a vet if necessary.

What Should Their Main Diet Consist Of?

Maintaining a balanced and nutritious diet is essential for the overall health and productivity of chickens. To ensure this, the cornerstone of their intake should be:

Layer Pellets or Mash: These specially designed feeds deliver all the essential proteins, vitamins, and minerals your chickens need for optimal health and robust egg production.

Grit: Acting as a chicken’s tooth, grit in the form of small stones or coarse sand, aids in grinding down food in their gizzard.

Fresh Water: Chickens must always have access to clean, fresh water. Proper hydration is integral to their health and particularly crucial for egg production.

Scratch Grains: Comprising a mix of grains such as corn, barley, oats, and wheat, scratch grains are a favourite amongst chickens. However, they should only be offered sparingly, especially during the colder months to help the birds stay warm.

Green Vegetables: Nutrient-dense leafy greens like spinach, lettuce, and kale provide a wealth of essential vitamins and minerals and can make an excellent treat for chickens.

Fruits: Incorporating a variety of fruits like apples and berries adds a refreshing element to their diet. You could even consider feeding oranges to chickens, which provide a vitamin C boost.

Calcium Supplements: For laying hens, an additional calcium source is critical to ensure they produce strong, healthy eggshells. This can be provided via oyster shells or even crushed eggshells.

It’s crucial to remember that treats, such as mushrooms, fruits, or other table scraps, should make up only about 10% of a chicken’s diet. The remaining 90% should stem from nutritionally complete chicken feed, ensuring they get all the necessary nutrients they need to thrive.

Where Can You Buy Chickens Food?

Finding quality chicken feed in the UK is a straightforward task, thanks to numerous retailers offering a wide range of poultry feed products. Here are a few reputable sources where you can purchase chicken food:

Green potatoes and green tomatoesThese can contain solanine, a compound that’s toxic to chickens when consumed in large amounts.
Dry beansUncooked or dry beans have a toxin known as phytohaemagglutinin, which can be deadly for chickens.
CaffeineDrinks like coffee and tea can overstimulate chickens’ cardiovascular system, leading to heart problems.
Mouldy or rotten foodMouldy or spoiled food can contain toxins that may cause serious health problems, including respiratory issues.
Rhubarb leavesRhubarb leaves contain oxalic acid, which can be toxic to chickens if consumed in large quantities.
SaltExcessive salt can lead to salt poisoning, which may result in dehydration, kidney damage, and even death in severe cases.

Feeding your chickens the right food is key to their health, wellbeing, and productivity. The foods listed above should be avoided to ensure that your chickens’ diet doesn’t harm them. Instead, stick to a balanced poultry feed supplemented with safe fruits, vegetables, and treats, ensuring your flock remains happy and healthy.


Feeding your chickens is more than just a task; it’s an art that balances providing a diverse range of foods while ensuring nutritional needs are met and potential dangers avoided. Mushrooms, as we’ve discovered, can be a safe and nutritious treat for your flock, provided they are of a variety safe for chickens and humans alike. However, like all treats, they should be given in moderation as part of a varied diet.

It’s vital to remember that the bulk of a chicken’s diet should come from high-quality poultry feed, supplemented sparingly with safe fruits, vegetables, and other treats. Be sure to avoid foods that can harm your flock, such as chocolate, onions, and green potatoes, amongst others.

Finally, always remember to keep an eye on your chickens when introducing any new food to their diet, and seek advice from a vet if you notice any changes in their behaviour or health. In doing so, you’ll ensure your flock stays as healthy, happy, and productive as possible.


Can Chickens Eat Cooked Mushrooms?

Yes, chickens can eat cooked mushrooms. However, ensure the mushrooms are cooked plainly without any seasoning or additives that could be harmful to chickens, such as onions, garlic, or excessive salt.

Are Wild Mushrooms Safe for Chickens?

Not all wild mushrooms are safe for chickens. Some wild mushrooms are toxic and can cause harm to chickens if ingested. As a rule of thumb, only feed your chickens the same mushrooms you’d safely eat yourself.

Can Mushroom Consumption Affect Egg Production?

While mushrooms can be a part of a chicken’s diet, they should not constitute a significant portion. A balanced diet with appropriate poultry feed is necessary to maintain optimal egg production. Mushrooms are a treat and should be given sparingly.

Is It Safe for Baby Chicks to Eat Mushrooms?

It’s advisable to introduce mushrooms into a chick’s diet only when they have fully matured. Baby chicks require a diet rich in proteins and other nutrients, typically found in specially-formulated chick feed, to ensure healthy growth.

Can Mushrooms Cause Allergies in Chickens?

Although rare, chickens, like any animal, could potentially have an allergic reaction to certain foods, including mushrooms. If you notice any unusual behaviour or symptoms after feeding mushrooms to your chickens, such as difficulty breathing, swelling, or changes in their droppings, consult a vet immediately.
