Wry neck (torticollis) is a twisted neck in a chicken, and it is a sign of a problem rather than a disease in itself: it can follow a nervous-system infection, a nutritional deficiency or an injury, so the cause decides what can be done. Some causes respond to diet changes or veterinary care. Others, such as virulent Newcastle disease, have no treatment and must be reported. This guide explains how to tell the difference and when to call for help.
Key Takeaways
- Wry neck means a twisted neck; it is a sign that needs a cause, not a diagnosis.
- Twisting of the head and neck is a warning sign of avian influenza and virulent Newcastle disease, which must be reported (USDA: 1-866-536-7593).
- Vitamin E deficiency damages the part of the brain that controls coordination and may respond to vitamin E if caught early.
- Stargazing (head drawn back) is a different sign, classically linked to thiamine (vitamin B1) deficiency.
- There is no surgery or home procedure that straightens a chicken’s neck; if a bird is suffering, humane euthanasia by a veterinarian is the kind option.
Correction: an earlier version of this article wrongly listed neck dislocation (a euthanasia method) and tendon-release surgery as treatments, suggested human painkillers, genetic testing and vitamin E oil rubbed on the skin, and did not mention that a twisted neck can signal reportable Newcastle disease or avian influenza.
What wry neck looks like
Torticollis is the medical term for a twisted or wry neck. An affected chicken holds its head at an odd angle, sometimes upside down, and may not be able to straighten it.
Because the bird cannot hold its head normally, you may also notice:
- Loss of balance, stumbling or falling over
- Walking backward or in circles
- Trouble reaching feed and water, followed by weight loss
- Tremors or weak, paralyzed wings or legs in some infections
Wry neck is not the same as stargazing. In stargazing the bird sits back on its legs with its head pulled back toward its back. Merck Veterinary Manual describes this star-gazing position as a classic sign of thiamine (vitamin B1) deficiency.
Common causes of a twisted neck
Infections that affect the nervous system
Virulent Newcastle disease can cause tremors, seizures, paralysis of the wings and legs, circling and torticollis. Merck notes that no medication has been shown to change the course of virulent infection. USDA also lists twisting of the head and neck, along with stumbling or falling, among the warning signs of avian influenza and Newcastle disease.
Vitamin E and selenium deficiency
Vitamin E deficiency can cause encephalomalacia, which damages the cerebellum, the part of the brain that controls coordination; the classic sign is loss of coordination (ataxia). Vitamin E and selenium work together in the body. Diets with little vitamin E, or with unstable fats that have oxidized, raise the risk.
Thiamine deficiency
A shortage of vitamin B1 causes nervous signs, including the stargazing posture described above. Severely affected birds may stop eating.
Head or neck injury
A blow to the head, a predator attack or a fight can also leave a bird with a tilted or twisted head. A veterinarian can check for injury while ruling out the causes above.
When to call your vet or the state veterinarian
Treat a twisted neck as potentially serious until you know the cause. Call right away if:
- More than one bird shows nervous signs such as twisting, tremors, stumbling or paralysis
- Birds are dying suddenly or in larger numbers than usual
- You also see swelling or purple color of the head, comb or wattles, gasping, sneezing, nasal discharge, green watery diarrhea or a sudden drop in egg laying
Avian influenza and virulent Newcastle disease must be reported. Contact your veterinarian, your state veterinarian, or USDA toll-free at 1-866-536-7593. Do not move birds on or off your property and avoid visiting other flocks until you have an answer.
If a bird dies, a state diagnostic laboratory can perform a necropsy (animal autopsy) to find the cause, often for a modest fee. Your vet or extension office can tell you where to send it. Our guide to biosecurity for chickens covers how to keep disease out of your flock.
How a veterinarian diagnoses wry neck
There is no single test for wry neck. A poultry veterinarian will ask about the flock, the feed and how many birds are affected, then examine the bird. A veterinarian or diagnostic laboratory may test sick or dead birds for infections such as Newcastle disease and review the diet for vitamin E, selenium or thiamine shortfalls.
Genetic testing is not used to diagnose wry neck, and vitamin deficiencies are a feed problem, not an inherited one.
Care and treatment options
What helps depends entirely on the cause:
- Separate the bird. Move it to a quiet, clean pen away from the flock so it cannot spread germs and will not be picked on.
- Make sure it eats and drinks. A bird that cannot aim its head may need feed and water placed where it can reach them easily, and may need help from a vet if it stops eating.
- Vitamin E, if deficiency is suspected. Merck reports that a single oral dose of vitamin E usually brings remission of encephalomalacia, but the response depends on how much brain damage has already occurred. Ask your vet about dose and whether selenium is needed. Vitamin E is given by mouth or in feed or water; rubbing vitamin E oil on the neck does not treat a deficiency.
- Thiamine, if a vet diagnoses B1 deficiency. Severe cases may need thiamine given directly by mouth or by injection.
- Pain relief only through a vet. Do not give a chicken human pain relievers on your own. Drugs not labeled for chickens are extra-label and need a veterinarian’s direction and an egg and meat withdrawal time.
If an infection is involved, remember that since June 2023 medically important antibiotics for animals in the US require a veterinarian’s prescription. For virulent Newcastle disease there is no treatment.
When euthanasia is the humane choice
There is no surgery, tendon procedure or home technique that straightens a chicken’s neck. If a bird is suffering, cannot eat or drink, or is not improving despite care, discuss humane euthanasia with your veterinarian.
Cervical dislocation is a recognized euthanasia method for small poultry. It ends the bird’s life; it does not reset the neck, and it must be performed only by someone trained in the procedure. A veterinarian can also perform drug-based euthanasia; call ahead to confirm they see poultry.
Preventing wry neck
- Feed a fresh, complete commercial ration made for your birds’ age, and do not use feed that smells stale or rancid; oxidized, unstable fats raise the risk of vitamin E deficiency. See our chicken feed guide for the basics.
- Ask your hatchery or veterinarian about Newcastle disease vaccination; live vaccines can be given from day 1.
- Practice biosecurity: isolate new birds before they join the flock, limit visitors, clean your shoes, avoid sharing equipment with other flocks and keep wild birds away.

FAQs
Can a chicken recover from wry neck?
It depends on the cause. Birds with vitamin E deficiency may improve with treatment, but Merck notes the response depends on how much brain damage has already occurred. Virulent Newcastle disease has no treatment.
Is wry neck contagious?
Wry neck itself is not contagious, but infections that cause it, such as Newcastle disease and avian influenza, are highly contagious. Separate the bird and call your vet or the state veterinarian if more than one bird is affected or birds are dying.
Is stargazing the same as wry neck?
No. Wry neck is a sideways or upside-down twist of the neck. Stargazing is when the head is pulled back toward the back, a classic sign of thiamine (vitamin B1) deficiency.
Can I give my chicken ibuprofen or aspirin?
Not on your own. Human medicines are not labeled for chickens, so any use is extra-label and must be directed by a veterinarian, who will also set a withdrawal time before eggs or meat can be eaten.
Who do I call if I suspect Newcastle disease?
Call your veterinarian, your state veterinarian, or USDA toll-free at 1-866-536-7593.
Conclusion
A twisted neck is a symptom that needs a cause. Rule out reportable diseases first, then work with a veterinarian on diet and supportive care. If a bird is suffering and not improving, humane euthanasia by a trained person or a vet is the kind choice.
