Chick Care: Why Are My Chicks So Tired?

what causes 8 week old chicks to be lathargic

Chicks are vulnerable and can easily become sick, so it's important to be able to recognize the symptoms of various illnesses to provide proper care. Lethargy in chicks can be caused by several factors, including coccidiosis, Marek's disease, respiratory illnesses, omphalitis, and pasty butt. Coccidiosis is an intestinal disease caused by parasites, while Marek's disease is a viral illness that causes weight loss, tremors, and paralysis. Respiratory illnesses, such as aspergillosis or brooder pneumonia, can also cause lethargy in chicks. Omphalitis is an infection of the navel that can occur soon after hatching, and pasty butt is a condition where loose droppings stick to the chick's vent, causing lethargy and listlessness. It's important to consult a poultry veterinarian for a proper diagnosis and treatment plan to ensure the health and well-being of your chicks.

Marek's disease

Vaccination is the best method of prevention. It is important to follow the instructions on the vaccine label, including the specified temperature and how quickly to thaw. The vaccine must be injected, usually under the skin, and every bird needs to get a full dose. The brooder should be clean and disinfected before placing the chicks. It is also important to wash hands, use a sterile needle, and avoid touching the needle to ensure the vaccine does not become contaminated.

Some breeding birds carry a resistance factor—B21—which can be detected through a blood test. However, genetic disease resistance takes decades to develop and has not yet been successful with Marek's disease.

Omphalitis

Lethargy in chicks can be caused by coccidiosis, an intestinal disease caused by parasites, or by omphalitis, a bacterial disease.

The infection occurs when bacteria enter the incubating eggshell. This happens when the incubator or associated equipment (such as the egg-turning device or thermometers) are not properly disinfected, when dirty eggs are set in the incubator, or when eggs are handled with dirty hands. Bacteria can also be introduced to the incubator by infertile or dead embryos, especially if they explode.

To prevent omphalitis, it is important to control the temperature, humidity, and sanitation in the incubator. Only clean, uncracked eggs should be set. If dirty eggs must be used, they should be kept separate from clean eggs and set at the bottom of the incubator. Sanitizing detergents should be used according to the instructions, with the concentration of sanitizer in the wash and rinse water being as critical as time and temperature. The rinse water should be warmer than the wash water, which should be warmer than the internal temperature of the egg, but not more than 60°C. The incubator should be thoroughly cleaned and disinfected between hatches.

Chicks with omphalitis may have an unhealed, swollen, or leaky navel, and their abdomen may be distended. They will be lethargic, with drooping heads, and will huddle near heat sources. They will fail to gain weight, and mortality rates will increase from hatch to two weeks old.

There is no specific treatment for omphalitis, and antimicrobial treatment is often ineffective.

Coccidiosis

The oocysts live in the soil, litter, feed, or water and can be spread by other chickens, rodents, insects, people, or even through air-blown dust and debris. They must be exposed to the correct conditions to become infective, which is a moist, warm environment. The oocysts are transmitted in droppings and can be spread via contaminated water, food, and poop.

Chickens with a compromised immune system are more susceptible to coccidiosis. Chicks between three and six weeks of age are most commonly affected, as they haven't built up natural immunity yet. Chicks older than six weeks should have a natural immunity to the parasite. Vaccination programs and medication programs can help reduce the incidence of coccidiosis in flocks. Anti-coccidial drugs (coccidiostats) are available for prevention and treatment and can be added to feed or water.

Pasty butt

To treat pasty butt, it is recommended to wash the chick's butt under lukewarm running water, being careful not to chill the chick. Gently coax the softened poop off without pulling to avoid tearing the chick's skin. After cleaning, dry the chick thoroughly and place it back in the brooder. A hair dryer on low heat can be used to dry the feathers, being cautious not to burn the chick's sensitive skin.

To prevent recurrence, a small amount of gentle oil can be applied to the vent area to prevent poop from sticking. However, some sources advise against using oils or Vaseline as it may attract the attention of other chicks, leading to a dangerous picking situation. Regular monitoring of the chick's hygiene is recommended instead.

While pasty butt is a common issue, it can be easily treated and chicks usually recover quickly if action is taken promptly.

Respiratory illnesses

Other common respiratory illnesses in chickens include Avian Influenza, Chlamydiosis, and Avian Tuberculosis, which can be spread by wild birds such as sparrows and finches. Symptoms of respiratory illness in chickens include coughing, sneezing, wheezing, difficulty breathing, and a rattling, congested (phlegmy) sound when breathing.

It is important to treat respiratory illnesses early, as recovery is rare without intervention. In addition, if left untreated, the illness may spread to the rest of the birds in your flock. Proper coop management and preventative care can reduce the risk of reinfection. For example, ventilation plays a large role in reducing the risk of respiratory infections. If ventilation is lacking, humidity created by the chickens and their feces will build up on the walls and windows, and an ammonia level higher than 25ppm is enough to damage cilia in the airways of chickens, allowing respiratory pathogens to colonize and cause disease.

Frequently asked questions

There could be several reasons why an 8-week-old chick is feeling lethargic. Marek's disease, a viral illness that is almost always fatal, can cause lethargy. Coccidiosis, a common intestinal disease, can also make chicks listless and is the most common cause of death in baby chicks. Other possible causes include respiratory illnesses, omphalitis, and pasty butt. If you suspect your chick is sick, consult a poultry veterinarian for a proper diagnosis and treatment plan.

Marek's disease typically causes weight loss, tremors, paralysis, and tumors in older chickens. Chicks infected with Marek's disease may experience weight loss despite a good diet and can die within about 8 weeks.

Coccidiosis is most easily detected by bloody feces or blood around the vent. Other symptoms include appetite loss, listlessness, pale skin color, and failure to thrive or grow.

Pasty butt, also known as pasting or pasted vent, is a condition where feces stick to the area around a chick's vent, causing gut impaction and constipation. It is often caused by stress from shipping, fluctuating brooder temperatures, or low-quality feed.

To prevent your chick from getting sick, maintain a clean environment with frequent bedding changes and sanitized water dishes and feeders. Avoid overcrowding, as this can stress young chicks and make them more susceptible to disease. Keep their brooder temperature between 70-75°F, and ensure they have adequate space of 1-2 square feet per bird.
