Vitamin A

Just like us, chickens need plenty of vitamin A as well. It not only maintains their growth but also improves egg production in hens. A lack of vitamin A in their diet could lead to weakness and decreased egg production.


Niacin has anti-inflammatory properties that benefit chickens. Without a proper amount of niacin in their diet, chickens can suffer from inflammation of the mouth cavity and bowed legs.


Riboflavin (or vitamin B2) is another essential nutrient that aids the quality of egg production. The deficiency of riboflavin leads to curly-toe paralysis in chickens.

Pantothenic acid

A deficiency of pantothenic acid can lead to Dermatitis and lesions on chicken’s feet and mouth.

Vitamin E

The lack of vitamin E can cause Crazy Chick Disease or Encephalomalacia in chickens.


Calcium is essential for the health of your chicken’s eggs. The deficiency of calcium can also cause rickets.

Copper and Iron

Without copper in their diet, chickens can suffer from Anaemia.


Zinc is a mineral that improves the health of your chicken’s feathers and bones.


Magnesium is an essential part of a chicken’s diet. The deficiency of magnesium can sometimes result in sudden death.


High-calorie foods can be harmful to your chickens if they consume too much of it. However, feeding them these in moderation is okay.

Persin: the real enemy of your pet

Avocado could be an ideal treat for your chickens if it wasn’t for persin.

What is persin? Persin is a naturally occurring fungicidal that is present in different parts of an avocado plant: leaves, bark, and seeds. While persin doesn’t harm humans fatally, it has an adverse effect on most pet animals.

Birds like chickens are more sensitive to this toxin. If your chicken consumes persin accidentally, these are the symptoms you should look out for:

  • Unrest
  • Weakness
  • Apathy
  • Disoriented plumage
  • Labored breathing
  • Increased heart rate
  • Myocardial tissue damage

In case your pet has eaten a larger quantity of it, it can suffer from Asphyxia (acute respiratory syndrome) and will most likely die within the next 48 hours. While the fruit of avocado contains this toxin in a very low concentration, with the skin and the seed being toxic to them, it’s better to be safe than sorry.


Is there a way to feed avocado to your chicken safely?

Feeding avocados to chickens

If you want to try feeding your chickens avocado, these are things you should be extremely careful about:

Remove the pit and skin

The pit and outer skin of avocado contain a concentrated amount of persin. Thus, you should remove them carefully.

Scoop it out

It is best to use a scoop to collect the fruit for feeding your chicken. That way, you can leave the parts of that is closest to the skin as an added caution.


Other foods you shouldn’t feed your chicken

Avocado is not the only human food that you shouldn’t be feeding your pet friends. Here is the list of other foods you shouldn’t try to feed your chicken:


The rhubarb plant is rich in oxalic acids that are toxic to many birds, including chickens. Oxalic acid affects the egg formation in birds. If your chicken eats their fruit or leaves, it can produce soft-shelled eggs.

White potato

White potatoes belong to the nightshade family, which is known for containing solanine, a highly toxic compound to certain animals and birds. Well-cooked potatoes lose their solanine content, but simply boiling them won’t solve the problem. Solanine destroys the red blood cell production in chickens and causes diarrhea and heart failure.

Raw dried beans

Raw beans contain hemagglutinin, a natural insecticide that is unhealthy for chickens. Cooked beans are fine for chickens.


Onion contains thiosulphate, a toxin that, like solanine, disrupts the production of red blood cells and even kill your chickens.

Chocolate and Coffee

Due to the presence of methylxanthines (theobromine and caffeine), both chocolate and coffee cause hyperactivity and an increase in heart rate in chickens.

Citrus fruits

Although these fruits (orange, lemon, grapefruit) are not toxic to chickens, they can have a derogatory impact on their egg production.

Salty food

Foods that are rich in salt are not good for your chicken’s health since they are not capable of ingesting too much salt.

  • Hyacinth
  • Rhododendron
