What are worms in Chickens?
Worms are a common problem in chickens, and they can have a serious impact on the health of your flock.
Worms are parasites that live in the digestive tract of chickens, and they feed on the blood and nutrients in the bird’s body.
There are several different types of worms that can infect chickens, including roundworms, tapeworms, and cecal worms.
Roundworms are the most common type of worm found in chickens.
They are long, thin worms that can grow up to several inches in length.
Roundworms can cause a range of health problems in chickens, including weight loss, poor egg production, and even death in severe cases.
Tapeworms are another type of worm that can infect chickens.
They are flat, ribbon-like worms that can grow up to several feet in length.
Tapeworms can cause a range of health problems in chickens, including weight loss, diarrhea, and poor egg production.
Cecal worms are a type of worm that lives in the ceca, which are small pouches located at the beginning of the large intestine in chickens.
Cecal worms can cause a range of health problems in chickens, including weight loss, diarrhea, and poor egg production.
Worms are typically spread through contaminated food and water, as well as through contact with infected birds.
It is important to take steps to prevent worm infestations in your flock, such as practicing good hygiene, providing clean water and food, and regularly deworming your chickens.
If you suspect that your chickens have worms, it is important to seek veterinary care right away to prevent the spread of the infestation and to ensure that your birds receive appropriate treatment.

Roundworms:
Roundworms are the most common type of worm found in chickens.
These worms can grow up to 8 inches long and live in the chicken’s digestive tract.
Roundworms can cause weight loss, poor growth, and diarrhea in chickens.
The eggs of roundworms can survive in the soil for up to a year, so it’s important to keep the chicken coop clean and free of feces.

The ceca are pouches located at the beginning of the chicken’s large intestine.
Cecal worms are generally not harmful to chickens and do not cause any symptoms.
However, heavy infestations can cause diarrhea and weight loss.
Gapeworms:
Gapeworms are a type of worm that live in the trachea of chickens.
These worms can cause respiratory distress, coughing, and gasping for air in chickens.
Gapeworms are often found in chickens that free-range or have access to contaminated soil.
Hair Worms:
Hair worms are a type of worm that live in the chicken’s digestive tract.
These worms are thin and thread-like and can grow up to 2 inches long.
Hair worms can cause weight loss and poor growth in chickens.
The eggs of hair worms are often found in the chicken’s droppings and can be spread to other chickens through contaminated soil.
Threadworms:

The different types of worms that can infect chickens and the recommended treatments:
Type of Worm | Symptoms | Treatment |
---|---|---|
Roundworms | Weight loss, poor egg production, diarrhea, lethargy | Deworming medication (such as fenbendazole or ivermectin) |
Tapeworms | Weight loss, diarrhea, poor egg production | Deworming medication (such as praziquantel or niclosamide) |
Cecal worms | Weight loss, diarrhea, poor egg production | Deworming medication (such as fenbendazole or ivermectin) |
Deworming Medication:
In addition to deworming medication, there are several other steps you can take to prevent and treat worm infestations in your flock:
- Practice good hygiene: Keep your coop clean and dry, and regularly remove soiled bedding and droppings.
- Provide clean water and food: Make sure your chickens have access to fresh, clean water and feed that is not contaminated with feces.
- Quarantine new birds: If you introduce new birds to your flock, quarantine them for a few weeks to ensure that they are not carrying any diseases or parasites.
- Rotate pastures: If your chickens free-range, rotate them to different pastures to prevent the buildup of parasites in the soil.

Does apple cider vinegar deworm chickens?
There is some anecdotal evidence that apple cider vinegar (ACV) may help to deworm chickens, but there is limited scientific research to support this claim.
However, ACV is known to have some health benefits for chickens, and it may help to support their immune system and promote digestive health.
ACV is thought to work as a natural dewormer by creating an acidic environment in the chicken’s digestive tract that is less hospitable to parasites.
It may also help to break down the protective coating of worm eggs, making them more susceptible to destruction by the chicken’s immune system.
To use ACV as a dewormer for chickens, you can add it to their drinking water. The recommended dosage is 1 tablespoon of ACV per gallon of water, and you should offer this solution to your chickens for 5-7 days. It is important to use raw, unfiltered ACV that contains the “mother” (a colony of beneficial bacteria) for maximum health benefits.
While ACV may have some health benefits for chickens and may help to support their immune system, it is not a substitute for regular deworming medication.
If you suspect that your chickens have worms, it is important to consult with a veterinarian and use appropriate deworming medication to treat the infestation.
Can I eat eggs from chickens with worms?
It is generally safe to eat eggs from chickens that have been infected with worms, as long as the eggs have been properly cooked.
Cooking eggs to an internal temperature of 160°F (71°C) should kill any bacteria or parasites that may be present.
However, it is important to note that chickens with worm infestations may be producing fewer and lower-quality eggs.
In addition, if the infestation is severe, it can have a negative impact on the health of the chicken, which can affect the quality of the eggs.
To ensure the safety and quality of your eggs, it is important to practice good hygiene when handling and storing them.
Always wash your hands before and after handling eggs, and store them in a clean, cool place (such as the refrigerator) to prevent the growth of bacteria.
If you are concerned about the health of your chickens or the safety of their eggs, it is always a good idea to consult with a veterinarian.
They can help you identify and treat any health issues in your flock and provide guidance on safe egg handling and storage practices.
