It would take hours of research and reading on the different foods chickens can and cannot eat. For the sake of saving you time, we’ve compiled one of the most comprehensive lists of foods that are safe to feed to chickens. We’ve also included foods that are waving red flags that you should stay away from!

Foods That You CANNOT Give To Your Chickens.

Let’s get the bad stuff out of the way before we go over foods that are safe to feed to chickens. It goes without saying that processed foods (junk food) are a big No-No for chickens. Junk food is high in sugar/carbs, salt, and chemicals that can be toxic/harmful for poultry of any kind.

For the sake of your feathered pets, you need to know what foods will kill chickens as well as what foods are poisonous/toxic for chickens.

Dry Beans/Legumes

Highly Toxic – can be fatal

NEVER give chickens dry beans.

Beans that are fully cooked are an excellent source of protein for your chickens. Boiling them for 10 minutes or more reduces toxins.

  • Toxin: Phytohemagglutinin (PHA)
  • Causes digestive distress in both humans and animals.
  • The kidney bean is extremely toxic with high fatal probability within two weeks of ingesting.
  • Castor beans contain ricin, which is used in bioterrorism.
Avocado Skin & Pit

HIGHLY Toxic – can be fatal

The avocado’s flesh is okay to give to your chickens but avoid giving them the skin or pit.

  • Toxin: Persin
  • Causes fluid to build up around the heart, problems breathing, organ failure, and inability to stand on a perch.
Salt and Salty Foods

Toxic – can be fatal

Sodium (salt) is required in the diet of chickens. However, too much salt causes salt poisoning.

Foods that fall in this category are nuts, chips, crackers, ham, pork, and more.

  • Salt toxicity
  • Causes severe depression, difficulty breathing, loss of coordination, and an increase in water consumption.
Caffeinated Foods/Drinks

Toxic – can be fatal

You should NEVER allow your chickens to eat or drink anything that contains caffeine. This includes coffee, coffee grounds, tea, tea grounds, and chocolate.

  • Toxin: Caffeine
  • Causes irregular heartbeat, increased heart rate, vomiting, agitation, tremors, seizures, and death.
Citrus Fruit Peel and Seeds


There’s a lot of debate in the poultry industry about the safety of citrus. Many chicken owners give their chickens small amounts of the fruit’s flesh.

Nightshade Plants

HIGHLY Toxic – can be fatal

  • Potatoes
  • Tomatoes
  • Tomatillos
  • Petunias
  • Eggplant
  • Peppers (of any type)
You should NEVER allow your chickens to consume raw nightshade plants.

  • Toxin: Solanine
  • Causes neurotoxicity, paralysis, respiratory distress, seizures, and death
Eggs Eating eggs (raw or cooked) doesn’t pose any danger for chickens. However, eating eggs should be discouraged because chickens will begin eating the eggs in the nesting boxes.
Plants (Toxic) Before you plant something, make sure it’s safe for your chickens.

There are numerous common plants, flowers, and vegetables lurking in a yard that are toxic to chickens.

Onions fall within these toxic plants.



Rhubarb is safe for chickens in minimal amounts. However, large portions are toxic.

  • Toxins: Oxalic acid, anthraquinone glycoside, and other toxins
  • Causes renal failure.
Seeds and Pits of Fruits

HIGHLY Toxic – causes death within a few minutes after ingesting

Fruit seeds/pits are one of the most dangerous things to feed a chicken.

  • Toxin: Cyanogenic glycosides (cyanide)
  • Causes immediate hypoxia.
