Chicken Wormer: Everything You Need To Know

What are the categories of chicken worms?

There are two main categories of chicken worms. These are the direct and indirect lifecycles of these internal parasites.

A worm with a direct lifecycles lives all its entire life inside the chicken intestines. Here, they feed, shelter and lay their eggs.

Chicken worm eggs have a special coating which prevents them from being destroyed by digestive enzymes.

They are passed out with chicken poop and remain on the ground until they are collected by other birds when free ranging.

On the other hand, any worm with an indirect lifecycle relies on another organism like snails and slugs to be passed in the chicken’s body.

This happens when chickens eat these organisms or other type of material they collect as food when free ranging.

What are the common types of chicken worms?

There are several common types of chicken worms. All these are harmful and can lead to ill health, low production or even death when not treated on time.

These include:

Tape worms

These are flat, long and segmented worms which can infest your chickens. Their body segments will break off and passed out together with poop.

The broken parts are collected and ingested together with the tasty treats chickens collect when free ranging.

Tapeworms can be collected from the poop of other farm animals like dogs, sheep and horses. They live along the intestinal walls and can grow to more than 30cm in length.

These worms will suck blood and other nutrients from the host’s body. This makes the infested birds weak, unkempt and emaciated.

Round worms

Round worms are the common type of worms in chickens. They like to cling on the small intestines where they will suck nutrients.

These worms have a direct lifecycle and they will live inside the chicken’s body. They will lay eggs and they will be eaten by another chicken and the cycle goes on.

Round worms are big and can grow to the length of 12cm. The worms can grow big and even lead to intestinal blockage.

Infected chickens will have pale combs, unkempt feathers, diarrhea and stunted growth.

Gape worms

Gape worms are a special type of chicken worms that infest the wind pipe. They are Y-shaped and can block the air way making the chicken gasp for air.

These worms will lay their eggs which are coughed in the mouth, swallowed and passed out with poop. A second bird will collect these eggs when pecking at the chicken coop and get infested too.

They will inhabit the windpipe and suck blood from the surrounding blood vessels. Infested birds will cough and gasp for air when breathing.

Sometimes, these chickens will produce a wheezing sound when the air way is blocked. Additionally, they will have rough coats and decreased appetite.

Eye Worms

Eye worms will infest chickens eyes where they prefer to live. They are small and hard to see with your naked eyes.

Infested birds will scratch the eyes and a whitish thick substance may come out. Birds will have a low appetite for food and droop their heads,

If not treated, eye worms can lead to blindness and eventually death. Seek advice from a qualified bird vet on the right medication to use.

How to control worms in chickens

There are a number of chicken treats that are known to remove worms in chickens. They include pumpkin seeds and cilantro.

These treats are chemical free, cheap and easily available.

Use dry bedding material

Dampness is a favorable environment for chicken worms to thrive. Use dry bedding material like pine shavings, chopped straw or hay.

Hang the chicken waterers to prevent chickens from kicking them and creating a dump environment. Have enough ventilation to allow free air circulation that will drive any moisture out.

Clean the coop

Clean your chicken coop regularly to remove any chicken poop. This will help you get rid of any worm eggs that may have been passed out when chickens defecate.

Clear the bush and trim the grass

The area in and around your compound where chickens roam and range should always be clean. This will deny slugs and snails a conducive environment to thrive in.

Additionally, any droppings dropped will dry easily and kill the eggs.

Apple cider vinegar is a remedy

Adding a few drops of apple cider vinegar is good for your chickens. It should be added in their water to discourage algae growth.

Do not throw food on the ground

Throwing chicken feeds in the ground should be avoided by all means. When eating, they can easily collect worm eggs and get infested.

Instead, use clean chicken feeders or open trays to feed your chicken breeds.

Sprinkle small amounts of diatomaceous earth

Diatomaceous earth is a good way to control parasites in chickens. Sprinkling small amounts of it in the chicken coop will kill the eggs as well as other parasites.

Deworm your chickens regularly

Chickens should be dewormed after every three months to keep them safe. You can also do it if you do a slide test on their poop and see any signs of worms.


Worms in chickens can cause great losses to poultry farmers. Birds will lose weight, lay fewer eggs and even lead to other health issues.

Always ensure that your birds live in a clean and tidy environment. This will deny any worm eggs or other organisms like snails to thrive.

If possible, confine your birds in a chicken run to stop them from free ranging. I know this is not easy because it helps bring down the cost of feeding them but it can help.

However, chickens are hardy birds and are not easily infested by worms. It is always advisable to seek advice from a qualified bird vet if worm infestation persists.
