When To Worm Chickens


Caring for chickens involves managing various aspects of their health, and one crucial consideration is their vulnerability to parasitic worms. These small but potentially harmful organisms, known as helminths, can take up residence in the digestive system of chickens, affecting their overall well-being. In this comprehensive guide, we will explore the intricacies of worm infestations in chickens, including their types, life cycles, symptoms, prevention, and treatment.

Do My Chickens Have Worms?

Before delving into the specifics of worm control and treatment, it’s essential to determine whether your chickens are affected by worms. These endoparasites can wreak havoc on your poultry flock, impairing growth, reducing egg production, and compromising overall health. Let’s begin by understanding how worms can find their way into your feathered companions’ digestive systems.

Discussion: Control and Treatment of Worms in Poultry

Chickens can host a variety of worm species, each with its own unique characteristics. To effectively manage these worms, it’s crucial to grasp their life cycles, modes of transmission, and the best practices for prevention and treatment.

Types of Worms

  1. Roundworms: These are common intestinal parasites found in chickens, capable of causing a range of health issues.
  2. Gapeworm: Named for their ability to infest a chicken’s respiratory tract, gapeworms can lead to breathing difficulties.
  3. Tapeworm: Tapeworms attach themselves to the chicken’s intestine and can affect nutrient absorption.
  4. Threadworm: These small worms can inhabit the crop and esophagus, causing discomfort.
  5. Cecal worms: Found in the ceca, these worms can impact digestion and overall health.

How Do Chickens Get Worms?

Understanding the pathways through which chickens acquire worms is crucial for effective prevention. Chickens can ingest worm eggs through contaminated droppings or by consuming insects that have ingested worm larvae. A chicken’s health and immune system also play a significant role in determining the severity of worm infestations.

The Life-Cycle of Worms

Worms follow intricate life cycles, often involving intermediate hosts such as insects. Disrupting these life cycles is a key strategy in controlling worm populations. Regularly moving the chicken coop and run, maintaining a clean environment, and keeping grass mowed can help break the cycle of infestation.

Signs and Symptoms

Recognizing the signs of worm infestations is vital for timely intervention. Chickens burdened with heavy worm loads may exhibit weight loss or gain, increased feed consumption, pale combs, and even gasping for breath due to gapeworm infestations. Conducting a fecal egg count can provide valuable insights into the extent of the infestation.


Preventing worm infestations is far more effective and humane than dealing with them after they take hold. Good animal husbandry practices, including regular cleaning of coops and runs, can significantly reduce the risk of worm problems. Using fresh bark or mulch in muddy areas can discourage parasite proliferation.

Natural Worming Remedies

For those looking to take a natural approach to worm prevention and treatment, several options are available. Garlic, known for its natural repellent properties, can help keep parasites at bay. Diamol, an organic compound, and apple cider vinegar, with its mild antiseptic and antibiotic qualities, can also be used. However, caution is advised when using apple cider vinegar.

When To Repeat Treatment

The timing and frequency of worming treatments depend on various factors, including the prepatent period of different worm species and their varying life cycles. To maintain optimal health, understanding these cycles is essential for developing an effective treatment schedule.

Worm Treatments – Remember to Treat the Whole Flock

When it comes to worm treatments, it’s essential to treat the entire flock to prevent reinfestations. Various commercial options are available, such as Aviverm, Pour On Drench, and Flubenol. Administering these treatments as per the manufacturer’s instructions is crucial for their effectiveness.

10 Tips To Keep On Top Of Worms

Preventing worm infestations requires a multifaceted approach:

  1. Proper Feeding: Providing a balanced diet can bolster chickens’ immune systems.
  2. Hygiene: Regular cleaning of feeders, drinkers, and living areas can reduce contamination risks.
  3. Coop Maintenance: A clean coop means fewer places for worms to thrive.
  4. Sunlight and Dry Conditions: Worm eggs struggle to survive in dry and sunny environments.
  5. Pasture Rotation: Moving chickens to fresh pastures can disrupt worm life cycles.
  6. Identify Worms: Learn to recognize different worm types to tailor treatment approaches.
  7. Regular Health Checks: Regularly monitor your chickens’ health to catch issues early.
  8. Quarantine New Birds: Isolating new additions can prevent introducing worms.
  9. Consult a Vet: Seek professional advice for effective worm management.
  10. Educate Yourself: Understanding worm types and life cycles empowers you to make informed decisions.
