Having a backyard flock of chickens is a great way to get fresh eggs.Chickens are terrific for keeping the bug population down. They even make rich compost for the garden.

They do all of this while providing great entertainment around the homestead! You want the best feed for chickens, to get the healthiest flock.

47 Things NOT To Feed Chickens To Keep Them Healthy * The Homesteading Hippy (1)

Most of the time, what to feed chickens is a no-brainer. Your local feed or farm supply store will often carry a poultry feed specifically made for laying chickens.

Adding fodder to their diet helps to cut down on the feed expenses. Fodder is rich in vitamins and minerals, meaning it’s a perfect supplement during the winter when grass is not available.

Many will give their chickens kitchen scraps as a way to supplement their diets, which ensures all your excess food is used efficiently. It’s a great way to help keep the feed bills down.

There are tons of treats you can spoil your chicks with, things like berries, leafy greens, bananas, and even citrus fruits.

However, there are foods that chickens should NOT eat. Some foods that are healthy for us are dangerous food for chickens. Other foods such as French fries are safe to eat, but provide little nutritional value.

What Not to Feed to Chickens

So here is a list of what not to feed your chickens…

1. Raw Potato Peels

Raw potato peels, especially green ones, can contain a toxic substance called solanine. Thischemical may be harmful to your flock, even deadly.

If you have a large number of peels, it is best to cook them first if you want to give them to the chickens. Or, you can compost them directly without giving them to the chickens.

2. Citrus

2.Citrus can be harmful to some chickens. That being said, our chickens have never liked it anyway.

We normally do not put citrus peels in our chicken bucket because we use them for making homemade cleaners and homemade lemon extract.

3. Raw or Dry beans

Raw or dry beans can be toxic to birds due toa poison they contain called hemagglutinin. However, cooking or sprouting the beans before serving them to chickens will kill this toxin.

If you choose to add cooked beans, it’s best to use homemade versus canned. Using your won beans lets you control the amount of extra sodium, which is not healthy for your backyard flock.

4. Dry Rice

Chickens that are fed dry rice are in danger of the rice blowing up when it is introduced to moisture in the bird’s stomach, potentially causing harm to the gut. We do give our chickens leftover COOKED rice, and they love this treat.

5. Avocadoes

Avocado skin and pit are another food that is dangerous food for chickens. Our chickens do not care much for avocados anyway. But, to be sure, we have been keeping them out of the chicken bucket.

Uncooked Eggs

Raw eggs to your chickens could result in your flock turning cannibal.They will eat their own eggs because of a deficiency in their diet or due to stress. Adding some oyster shells or even the crushed egg shells back into their diet can help.

7. Apple Seeds

Apple seeds contain cyanide, which makes it a dangerous food for chickens. In small amounts, apple seeds are usually not an issue. But, chickens are not known for their self-control when eating apple bits.

We try to make sure the seeds from the cores do NOT make it to the chicken bucket. We aren’t perfect at this. The occasionalapple seed still gets in there. Still, it’s better to be safe than sorry.

8. Chocolate (or any kind of candy)

So a piece of candy here or there probably won’t do your chickens any harm – but it’s not going to benefit them in any way.

Chocolate, on the other hand, can be seriously detrimental for your flock’s health. Chocolate is famous for being toxic to dogs because it contains Theobromine. This is the compound that makes dogs sick, and it can also make your poultry sick, too.

9. Moldy Food

This should go without saying, but don’t feed your chickens anything that you would not eat yourself. If it’s rotten or moldy, toss it out. Don’t make your chickens clean it up for you.

10. Tomato or eggplant leaves

You should avoid feeding your chickens the leaves, stems, or raw fruits from tomato or eggplant plants.

These are both members of the nightshade family and can present dangerous symptoms to your chickens. They can be toxic when eaten raw, as the solanine they contain can kill your chickens.

11. Onions

Chickens should not be fed onions. Onions contain a toxin known as thiosulphate that can destroy your hen’s red blood cells. This can cause jaundice or anemia.

12. Coffee or tea bags

Some people advocate for feeding their chickens coffee grounds or tea bags. In small quantities this might be okay, but if there is any caffeine in the tea you need to steer clear.

Caffeine is a methylxanthine that can cause your chickens some serious health problems.

13. Anything that isn’t good for you

Okay, so you might not think of mealworms as being good for you – that’s probably the one exception to this statement. But you should avoid feeding your chickens any foods that you might like, but are bad for your health.

Foods and beverages like alcohol, salty treats, sweet desserts, or fried food fall into this category. It may not affect your chickens overnight, but it will cause some weight problems and other health issues later on down the line.

14. Anything sprayed with chemicals

You can safely feed your chickens lawn clippings or weeds – in fact, they’ll love them! However, if any of these have been treated with chemicals, you’ll want to avoid doing so.

15. Asparagus

Asparagus may not cause any issues when you feed it to your flock, particularly if you are raising broiler birds.

However, if you are raising chickens for egg production, you may want to avoid feeding them asparagus. It can taint the taste of your eggs.

16. Lettuce in large quantities

Lettuce (including iceberg lettuce) is fine in small quantities, but when fed in large amounts to your chickens, it can cause diarrhea, since it has so much water.

Instead, feed more nutritious options like kale, cabbage, and collards. You also need to avoid feeding too much spinach, which can inhibit calcium uptake. Other dark, leafy greens are safe.

17. Rhubarb and rhubarb leaves

Rhubarb can be toxic to chickens in large amounts. It contains oxalic acid which can kill your birds, as well as anthraquinones which act as a laxative.

18. Horseradish

Although it may seem harmless, horseradish, particularly horseradish leaves, can irritate a chicken’s digestive system, leading to vomiting and diarrhea. In severe cases, it can even cause death.

19. Amaranth

Many people believe that feeding amaranth to their chickens is a great way of providing them with healthy grains.

While it won’t necessarily harm your birds, amaranth contains antinutrients that can suppress the growth of your birds. If you cook it, however, it reduces those nutrients so that it is safe for your birds to eat.

20. Butter

Do not feed your chickens butter. Unlike most dairy products, which are good for your chickens, you should avoid butter, since it is high in fat and low in other nutrients.

21. Cherries

You can feed your chickens cherry fruits, but you need to avoid feeding them the pits of the cherries. Like apple seeds, these contain cyanide.

22. Raw chicken

You can feed chicken other meats, including chicken, in most cases. However, it should always be cooked, as raw chicken can carry the risk of salmonella.

Feeding chickens these items by accident will probably NOT hurt your flock. If you have, don’t worry too much about it. Try and keep these foods out of the chicken bucket in the future if you can. Error more on the safe side.

23. Green potatoes

Green potatoes contain high amounts of solanine, a compound we mentioned before as being very toxic to chickens.

Avoid feeding them green potatoes at any cost, else it will attack their nervous system and lead to some horrible things such as paralysis.

Instead, you can just throw these into your compost pile.

24. Excess salt

Chickens are very sensitive to salt and it can cause serious health problems if they eat too much of it. It can increase their thirst, and make them more prone to dehydration. It can also cause kidney damage, and even death.

So, if you’re raising chickens, be sure to avoid giving them any food that is high in salt content. This includes table scraps, as well as commercial chicken feed that may have added salt.

25. Garlic

One foodstuff that chickens should avoid is garlic, as it can cause a number of problems.

First of all, garlic is very pungent and strong-smelling, which means that it can make the chicken’s eggs taste off.

Secondly, garlic is known to be toxic to chickens in large quantities, so it’s best to err on the side of caution and avoid feeding it to them altogether.

26. Soda and juice

Chickens should never be given soda or juice. These drinks are high in sugar and can cause health problems, including diabetes and obesity. In addition, the acidity of soda and juice can damage a chicken’s digestive system.

27. Alcohol

This one might sound obvious, but believe it or not, a lot of people wonder if they can give their chickens a beer or two on a hot summer day.

The short answer? Absolutely not. Alcohol can be dangerous to chickens for a variety of reasons. First, alcohol can cause dehydration, which can lead to death in chickens.

Second, alcohol can suppress the immune system, making chickens more susceptible to disease. Third, alcohol can cause liver damage in chickens. Finally, alcohol can negatively impact the gastrointestinal system, leading to diarrhea and other problems.

28. Chips and pretzels

Both of these snacks are high in salt and fat, which can lead to health problems in chickens. In addition, the MSG in many chips and pretzels can also be harmful to chickens.

29. Uncooked pasta

Chickens should not eat uncooked pasta. Pasta is made from wheat, which is difficult for chickens to digest.

When eaten uncooked, it can cause digestive issues and even choke the chicken. In addition, the pasta will absorb water from the chicken’s stomach, leading to dehydration

30. Seeds and pits

Seeds and pits can be harmful to chickens because they can contain toxins (like cyanide) that can make the chickens sick. In addition, seeds and pits can cause choke or blockage in the chicken’s digestive system.

31. Lawn clippings

Lawn clippings can contain pesticides and other chemicals that can be harmful to chickens. In addition, lawn clippings are generally low in nutrients and can actually cause malnutrition if chickens rely on them as their sole source of food.

For these reasons, it is best to avoid feeding chickens lawn clippings. If you do choose to feed them lawn clippings, make sure that the lawn is organic and free of pesticides.

32. Toads

Toads can be toxic to chickens. The poison is found in the toad’s skin, so even if you remove the skin before feeding it to your chicken, the poison can still be present. This can cause serious health problems for your chicken, and in some cases, death.

33. Acorns

Acorns should be avoided as chicken feed for several reasons. First, they contain high levels of tannins, which can make chickens sick. Second, they can interfere with the absorption of other nutrients, leading to deficiencies.

34. Mushrooms

Chickens are omnivorous animals and will readily eat a variety of foods, including mushrooms.

However, feeding chickens mushrooms is not recommended, as they can be poisonous to these animals. Ingesting poisonous mushrooms can lead to liver and kidney damage in chickens, and can even be fatal.

There are many species of mushrooms that are safe for chickens to eat, so there is no need to take the risk of offering them mushrooms that may be harmful.

If you are unsure whether a particular mushroom is safe for chickens, it is best to err on the side of caution and avoid feeding it to them.

35. Periwinkle

Periwinkle contains a substance called saponin, which can be toxic to chickens. In addition, periwinkle can also cause gastrointestinal distress in chickens, leading to diarrhea and vomiting.

36. Xylitol

Chickens are very sensitive to sweeteners, and xylitol is no exception. This sugar alcohol can be found in a variety of products, including chewing gum, candy, and baked goods.

While it is safe for humans, xylitol is toxic to chickens and can cause serious health problems.

Even a small amount of xylitol can lead to liver failure, so it’s important to avoid feeding it to your chickens.

37. Taro

Taro contains a toxic compound called oxalic acid, which can cause kidney damage in chickens.

In addition, taro leaves contain high levels of calcium, which can lead to calcium deficiencies in chickens. As a result, it’s important to avoid feeding chickens taro.

38. Ivy

Ivy can be toxic to chickens. Ivy contains a substance called saponin, which can cause vomiting and diarrhea.

39. Hyacinth

Hyacinth, on the other hand, contains a compound called lycorine that can cause respiratory problems.

40. Hydrangea

Though feeding chickens hydrangea may seem like a harmless way to provide them with extra nutrients, there are actually a few reasons why it is not recommended.

First of all, hydranagea is a member of the plant family Caprifoliaceae, which also includes key lime and Honeysuckle.

These plants contain toxic compounds known as grayanotoxins, which can cause severe gastrointestinal distress in chickens

41. Bracken Fern

While chickens are known to eat just about anything, there are some things that they should not eat. Bracken fern is one of them.

This plant contains a substance that can be toxic to chickens, causing problems with their digestion and respiratory system. In severe cases, it can even be fatal.

42. Castor Bean

These beans contain a substance called ricin, which is highly toxic to chickens. Just a few beans can cause severe illness or death. Symptoms of ricin poisoning include difficulty breathing, lethargy, and vomiting.

43. Lantana

This flowering plant is commonly found in gardens and is poisonous to chickens. Lantana can cause liver damage and death in chickens, so it is best to avoid feeding it to them. If you have lantana in your garden, make sure that your chickens cannot access it.

44. Apricot Plants

Chickens are attracted to the smell of apricots, and will often peck at the plants in search of the fruit. However, apricot plants can be harmful to chickens if ingested.

The leaves and pits of apricot plants contain cyanogenic glycosides, which release cyanide when they come into contact with digestive enzymes.

This can lead to cyanide poisoning in chickens, which can be fatal. In addition, apricot pits can also cause choking or blockages in a chicken’s digestive system.

45. Green Tomatoes

The unripe fruit contains high levels of solanine, a poisonous compound that can cause gastrointestinal distress and neurological problems. While a small amount of green tomato is not likely to kill a chicken outright, it can still make them very sick.

46. Oak

Oak contains high levels of tannins, which can be toxic to chickens in large quantities. Tannins can cause liver damage and gastrointestinal distress, and can even lead to death. For this reason, it is best to avoid feeding chickens oak leaves or again, acorns.

47. Tulips

Tulips contain a substance called lycorine, which can cause gastrointestinal distress in chickens. Symptoms include vomiting, diarrhea, and lack of appetite. In severe cases, lycorine poisoning can lead to organ damage and even death.

What Treats Are Better for Chickens: Alternatives to Consider

So now that we’ve told you what NOT to feed your chickens, you might be wondering, “geez, what’s left?” Here are a few smart alternatives.


In general, leafy greens are a good source of vitamins and minerals, while root vegetables like carrots provide a good source of energy. Here is a list of some specific vegetables that are safe to feed to chickens:
