What is Gapeworm and How Does it Affect Chickens?
Gapeworm is a highly contagious parasite that can seriously impact your chicken’s health, so let’s explore what causes these symptoms. We’ll dive into the specifics of how gapeworm affects chickens.
Definition and Prevalence of Gapeworm
Gapeworm is a type of parasitic infection that affects the respiratory system of chickens. It’s caused by the presence of the parasite Syngamus trachea, which attaches itself to the lining of the chicken’s trachea and esophagus, causing damage and inflammation. Gapeworm is one of the most common health issues affecting backyard flocks and commercial poultry operations worldwide.
The prevalence of gapeworm varies depending on factors such as geographical location, breed, age, and management practices. According to a study published by the American Poultry Research Association, gapeworm was found in 27% of chickens tested from small-scale farms in the United States. Another study in Europe reported that 35% of chicken flocks were infected with gapeworm.
Chickens of all ages can be affected by gapeworm, but young birds are more susceptible due to their immature immune systems. Breeds such as Leghorns and Rhode Island Reds are particularly prone to infection. If you suspect your flock is at risk, it’s essential to identify the signs and symptoms early on to prevent further complications.
Symptoms of Gapeworm Infection in Chickens
Chickens infected with gapeworm often exhibit noticeable symptoms that can indicate the presence of this parasitic infection. One of the most common signs is a persistent coughing spell, which may occur throughout the day or even at night. This cough is usually accompanied by difficulty breathing, as the worms block airways and make it hard for your chickens to breathe.
Weight loss is another symptom that’s often seen in gapeworm-infected chickens. Due to the parasite’s presence, they may have trouble consuming their regular diet, leading to a decrease in weight over time. This can be especially concerning if you’re raising chicks or pullets, as they require adequate nutrition for growth and development.
Lethargy is also a common symptom of gapeworm infection in chickens. Infected birds often appear sluggish and lack the usual energy level, which may be due to the constant strain on their respiratory system. In severe cases, you might notice that your chickens are reluctant to move around or engage in normal activities like foraging or exploring their coop.
If you suspect a gapeworm infection based on these symptoms, it’s essential to have your flock checked by a veterinarian as soon as possible.
Causes and Risk Factors for Gapeworm Infection
To protect your flock, it’s essential to understand what causes gapeworm infection and which factors increase their risk of contracting the parasite. Let’s explore these crucial topics together.
Sources of Infection: Contaminated Environment and Poor Hygiene
Gapeworm eggs can contaminate feed, water, and living spaces through various means, leading to infection. This is particularly concerning for backyard chicken keepers who may not have a robust biosecurity plan in place.
When it comes to contaminated feed, gapeworm eggs can be present on the surface of grains or mixed into feed during processing. If your chickens are fed from a communal feeder or trough, there’s a higher risk of them ingesting infected particles. Similarly, if you’re using treated straw or hay as bedding material, it may become contaminated with gapeworm eggs, which can then be transferred to the living space.
To minimize this risk, ensure that feed is stored in rodent-proof containers and kept clean at all times. Regularly cleaning and disinfecting feeding equipment is also crucial. As for water sources, ensure that they’re free from contamination by changing the water frequently and using a reliable water filter system if necessary.
Weakened Immune Systems and Other Contributing Factors
Chickens with weakened immune systems are more susceptible to gapeworm infections. A poor diet can compromise their immunity, making them more vulnerable to internal parasites like gapeworms. For instance, a lack of essential nutrients such as vitamin E and selenium can impair the immune function in chickens.
Genetics also play a role in determining an individual chicken’s susceptibility to gapeworm infection. Some breeds are naturally more resistant than others, but even within these breeds, certain individuals may be more prone to the disease due to their genetic makeup.
Stress is another significant contributing factor to weakened immunity in chickens. Chronic stress can suppress the immune system, making it harder for the bird’s body to fight off pathogens like gapeworms. This is often caused by factors such as overcrowding, poor living conditions, and inadequate lighting.
Age also plays a role in susceptibility to gapeworm infection. Younger chickens are more prone to internal parasites due to their underdeveloped immune systems.
Identifying Gapeworm Symptoms: Signs and Indicators
Recognizing the signs of gapeworm is crucial, so let’s dive into the common symptoms you should look out for in your flock. These indicators can help you identify if your chickens have been affected by this parasite.

Typically, the first sign of gapeworm is a decrease in appetite or lethargy. Chickens infected with gapeworm may appear off-color, losing their usual luster and vibrancy. You may notice them hiding more often, avoiding food and water sources, or showing little interest in their surroundings.
In some cases, you might observe a change in the chicken’s respiratory pattern, such as rapid breathing, wheezing, or coughing. These symptoms can be indicative of a gapeworm infection, particularly if they’re accompanied by a decrease in overall activity levels.
If you notice any of these early warning signs, it’s essential to take immediate action. Isolate the affected bird(s) from the rest of the flock and monitor their condition closely. Administering a dewormer specifically designed for gapeworm can help alleviate symptoms and prevent further complications. Regular health checks and maintaining a clean coop environment are also crucial in preventing gapeworm infections.
Advanced Stages of Gapeworm: Recognizing Severe Cases
In advanced stages of gapeworm infection, chickens may exhibit severe respiratory issues and secondary infections that can be life-threatening if left untreated. Recognizing these symptoms is crucial to intervene promptly and save the bird’s life.
Chickens suffering from advanced gapeworm infection may have difficulty breathing, displaying rapid or labored breathing patterns, wheezing sounds, or even complete cessation of breath. In severe cases, birds may also exhibit signs of respiratory distress, such as gasping for air, blue-tinged beak and legs, or collapse.
Secondary infections are common in advanced gapeworm cases due to the compromised immune system of the infected bird. These secondary infections can manifest as eye lesions, sinusitis, or peritonitis, among others. It is essential to inspect the bird’s body thoroughly for any signs of these complications and seek immediate veterinary attention if suspected.
In addition to addressing respiratory issues, treating advanced gapeworm cases also requires a comprehensive approach that includes supportive care, dietary adjustments, and targeted medication to control secondary infections.
