Wry neck, also known as torticollis, twisted neck, or stargazing, is a condition that affects chickens of all ages, causing their necks to twist or contort. While the condition can be alarming to farmers, it is treatable and rarely fatal. Wry neck is often caused by vitamin deficiencies, particularly a lack of vitamin E, but can also be the result of genetic disorders, head injuries, or exposure to toxins. Treatment for wry neck involves separating the affected bird from the flock and providing it with vitamin supplements, which can lead to improvement within 24 hours, but full recovery can take up to a month. So, while there may not be specific meat withdrawal guidelines for wry neck in chickens, the condition does require prompt attention and care to ensure the bird's survival and well-being.

What You'll Learn
Wry neck is a symptom, not an illness
Wry neck, also known as torticollis, twisted neck, or stargazing, is a distressing condition that affects chickens' neck muscles, causing their heads to twist or tilt to one side. It is important to note that wry neck is not an illness in itself but rather a symptom of an underlying issue.
Wry neck can be caused by various factors, including nutritional deficiencies, head injuries, genetic factors, and infectious diseases. One of the leading causes is a nutritional deficiency, particularly a lack of vitamin E and selenium, which are critical for muscle function and nerve health. Vitamin B1 (thiamine) deficiency has also been linked to wry neck, especially in chicks fed medicated chick feed for extended periods.
Head injuries, such as trauma to the head or neck, can damage nerves and muscles, leading to wry neck. Certain chicken breeds, like Silkies and Polish chickens, are more susceptible to head injuries due to their vaulted skulls.
Genetics also play a role, with some breeds being more prone to developing wry neck due to genetic factors. Additionally, wry neck can be a secondary symptom of infectious diseases such as avian encephalomyelitis or Marek's disease, which affect the nervous system.
Treating wry neck requires patience and dedication. It is crucial to separate the affected bird from the flock to prevent stress and accidental injury from other chickens. During treatment, it is common to have to assist the bird with eating and drinking, as their neck twist makes movement difficult. Administering vitamin supplements, particularly vitamin E and selenium, is essential for treatment. While improvements may be seen within 24 hours, complete recovery can take up to a month, and vitamin supplements should be continued for a further two weeks to ensure the bird's full recovery.
In summary, wry neck in chickens is not an illness but a symptom with various underlying causes. Prompt identification, separation from the flock, vitamin supplementation, and supportive care are key to successfully treating this distressing condition.

Wry neck is caused by vitamin deficiencies
Wry neck, also known as "crook neck", "twisted neck", or "stargazing", is a condition that affects chicks, chickens, and other poultry. It causes the bird to lose control of its neck, making it difficult for them to hold their head up. This can lead to difficulty in standing, walking, eating, and drinking, and in severe cases, even death.
Wry neck is often caused by a vitamin deficiency, particularly a lack of vitamin E. Vitamin E is essential for maintaining the health of chickens, and a deficiency can result in wry neck. It is recommended that chicken diets include between 10 and 25 IUs of vitamin E. Natural sources of vitamin E include sunflower seeds, which also provide selenium, an important mineral that aids in the absorption of vitamin E.
In some cases, wry neck can be caused by a deficiency in vitamin B-1, also known as thiamine. This vitamin is crucial for chicken health, and a lack of it can lead to the development of wry neck. Brewer's yeast is an excellent natural source of thiamine, and it can be found in cereal grains and their by-products.
Additionally, chicks may be more prone to vitamin deficiencies if their parents' diets were deficient in vitamins. It is important to ensure that breeding chickens have a healthy and varied diet to reduce the risk of vitamin deficiencies in their offspring.
Treating wry neck caused by vitamin deficiencies involves supplementing the affected bird's diet with the necessary vitamins and minerals. It is recommended to separate the bird from the rest of the flock during treatment to reduce stress and bullying. Vitamin supplements should be administered at least 2 to 3 times a day, either added to their feed or water. Improvement in the bird's condition may be seen within 24 hours, but it can take several weeks for a complete recovery.

Wry neck can be caused by head injuries
Wry neck, also known as "crook neck," "twisted neck," or "stargazing," is a frightening condition that affects chickens of all ages. It is caused by neck muscles spasming and pulling the head and neck into unnatural positions. While wry neck is typically associated with vitamin deficiencies or genetic disorders, it can also be caused by head injuries.
Head injuries are a common cause of wry neck, especially in older chickens. When a chicken sustains a head injury, it can result in serious swelling and pressure within the skull, leading to neurological problems. These neurological issues can cause the chicken to hold its head at an odd angle, a characteristic symptom of wry neck.
Chicken breeds with crests, or a crown of feathers on their heads, are more prone to head injuries. Their crests can be a target for feather pecking, and they have less bony skulls, which can leave their brains vulnerable to injury. If a chicken with an incomplete skull bone sustains a head injury, the resulting swelling and pressure can lead to the neurological issues associated with wry neck.
In some cases, wry neck caused by a head injury may not be curable. However, it is important to consult a veterinarian to determine the severity of the situation. Anti-inflammatory treatments can help reduce swelling in the skull, and if the brain was not damaged, the bird may recover from both the head injury and wry neck.
While there is no specific mention of meat withdrawal for chickens with wry neck, it is important to note that wry neck can cause difficulty in eating and drinking. Therefore, it may be necessary to separate the affected bird from the flock and assist it with feeding during the healing process.

Wry neck can be genetic
Wry neck, also known as torticollis, is a condition that affects newborn chicks and sometimes even full-grown chickens. It is characterised by a twisted neck that causes the bird to lose control of its neck and hold its head up. While wry neck in chickens is typically caused by vitamin deficiency, head injuries, or ingesting toxins, it can also have a genetic component.
Wry neck can be congenital, meaning it is present at birth, or acquired later in life. Congenital wry neck can be inherited or develop in the womb due to the baby's head being in the wrong position. It is often associated with genetic conditions such as congenital loco, where chicks hatch with the inability to stand or balance due to a recessive gene causing a malformation of the ear structure.
In chickens, wry neck can be indirectly linked to genetics, especially in crested breeds like Silkies. These breeds have a "vaulted" skull, which leaves a hole in the bones of the skull, similar to a fontanel in humans. This skull structure makes the bird's crest bigger but also increases its susceptibility to head injuries, which are a common cause of wry neck.
Additionally, vitamin deficiencies, particularly a lack of vitamin E, have been linked to wry neck in chickens. These deficiencies can be inherited if the parent chickens' diet was also deficient in vitamins, increasing the genetic predisposition for wry neck in their offspring.
While wry neck in chickens is often treatable with vitamin supplements and separation from the flock, it is important to recognise the potential genetic influences on this condition. By understanding the genetic component, breeders can make informed decisions to improve the health and well-being of their flocks.

Wry neck treatment: separate the bird and provide vitamins
Wry neck, also known as "crook neck", "twisted neck", or "stargazing", is a frightening condition that affects chickens' neck muscles, causing their heads to loll about. It can be caused by a variety of factors, including genetic disorders, vitamin deficiencies, head injuries, or ingestion of toxins.
If you notice that a chicken has wry neck, it is important to separate them from the rest of the flock. This will prevent them from being bullied or pecked by other chickens, which can be stressful for the bird. It is also important to provide them with vitamins, particularly vitamin E and selenium, as a deficiency in these vitamins is often the cause of wry neck. Vitamin E can be purchased as 400 IU capsules and added to the chicken's feed, or it can be given in the form of uncooked egg whites. Selenium can also be provided in the form of uncooked egg whites.
In addition to vitamin E and selenium, there are other vitamins that can be beneficial for treating wry neck. Vitamin B1 (thiamine) deficiencies have been linked to wry neck, so supplements like brewer's yeast, cereal grains, and by-product meals can be helpful. Vitamin D deficiencies may also be a factor, so providing outdoor time in the sunshine can be beneficial. Poly-Vi-Sol, an infant and toddler multivitamin, can also be added to the chicken's diet to provide a range of vitamins. However, it is important to avoid the version with iron.
It is important to be patient during the treatment process, as wry neck can take time to heal. Symptoms may fluctuate and get worse before they improve, but with proper care, most chickens will recover from wry neck. It is recommended to continue providing vitamin supplements for a few days after the bird recovers to ensure their health is back to normal.
