Raising chickens can be a fun and rewarding experience, but keeping them healthy requires careful attention to their diet. While chickens will eat almost anything, some foods can be harmful or even deadly to them. Knowing what to avoid can help prevent health problems and keep your flock happy.
Here’s a list of 10 foods that you should never feed your chickens and why they can be dangerous.
Foods That Are Toxic to Chickens
1. Candy and Chocolate
Chocolate might be a tasty treat for humans, but it’s toxic for chickens. It contains theobromine, a compound that chickens cannot process, leading to vomiting, seizures, and even death.
2. Avocado (Skin & Pit)
The skin and pit of avocados contain persin, a toxin that can cause heart failure, breathing difficulties, and weakness in chickens. High doses of persin can be fatal within 12–24 hours. Keep this “superfood” away from your flock.
3. Coffee and Tea
Caffeinated drinks like coffee and tea can cause heart arrhythmias and even death in chickens. Their bodies aren’t built to handle caffeine, so it’s best to keep your morning cup away from them.
4. Apple Seeds
Apples are a great treat for chickens, but their seeds contain amygdalin, which releases cyanide when digested. Remove the seeds before feeding apples to your flock. The same rule applies to seeds from pears, plums, peaches, and cherries.
5. Raw or Green Potatoes and Potato Peels
Raw potatoes, especially green ones, contain solanine and chaconine—both toxic to chickens. These compounds can cause digestive issues and illness. Always cook potatoes before giving them to your flock.
6. Onions and Garlic
Onions and garlic contain compounds that can cause anemia in chickens. While small amounts may not be harmful, regular consumption can lead to serious health problems.
7. Rhubarb Leaves
Rhubarb leaves contain oxalic acid, which interferes with calcium absorption. This can lead to kidney failure and even death in chickens. Always avoid rhubarb leaves when choosing treats for your flock.
8. Excessively Salty Foods
Chickens need a little salt in their diet, but too much can cause dehydration and kidney problems. Avoid giving them salty foods like chips, pretzels, or processed leftovers.
9. Dried Rice or Beans
Uncooked rice or beans can expand in a chicken’s digestive system, leading to blockages that can be fatal. Always cook rice and beans before offering them to your chickens.
10. Nightshade Vegetable Leaves and Stems
Plants like tomatoes, eggplants, potatoes, and peppers belong to the nightshade family. While the ripe fruits are safe, the leaves and stems contain solanine, a toxic compound that can cause digestive upset and weakness. Other plants like foxglove and yew are also dangerous for chickens.
Foods to Limit or Avoid for Chickens
While some foods aren’t necessarily toxic, they should be limited in your chickens’ diet to keep them healthy.
1. Rotten or Spoiled Vegetables
Never give chickens moldy or rotten food. Spoiled veggies can cause food poisoning and botulism, leading to paralysis or even death.
2. Dairy Products
Chickens can eat small amounts of dairy like yogurt, but they struggle to digest lactose. Too much dairy can cause digestive problems such as diarrhea.
3. Bread
Bread has little nutritional value and can fill chickens up, preventing them from eating nutrient-rich food. Overfeeding bread can lead to malnutrition or obesity.
4. Raw Peanuts
Raw peanuts contain harmful enzymes and, if moldy, can produce aflatoxins that damage the liver. If feeding peanuts, make sure they are roasted and unsalted.
5. High-Fat or Sugary Foods
Sugary treats like pastries and cakes can lead to obesity and reduced egg production. Keep these foods to a minimum.
6. Corn and Sunflower Seeds
While chickens love corn and sunflower seeds, they are high in fat and starch. Overfeeding them can cause weight gain and digestive issues. Limit these treats to a few times a week.
7. Raw Eggs
Feeding raw eggs can encourage chickens to eat their own eggs, a difficult habit to break. Avoid giving raw eggs to your flock.
8. Citrus Fruits
Citrus fruits like oranges and lemons contain citric acid, which can irritate a chicken’s digestive system. Some believe too much citrus can reduce egg production, so limit their intake.
Keeping your chickens healthy starts with a well-balanced diet. While they enjoy a variety of foods, some can be harmful or even fatal. Avoid feeding them toxic foods like chocolate, avocados, and raw potatoes, and limit treats that are high in salt, fat, or sugar.
Instead, focus on nutrient-rich foods like grains, vegetables, and protein sources to keep your flock happy and productive. By following these guidelines, you can ensure your chickens stay in top health and continue providing fresh eggs for years to come.
