Wry neck in chickens, also called torticollis, is treatable in most cases when caught early. The condition causes a chicken’s head and neck to twist sideways or backward, leaving the bird unable to walk, eat, or drink normally. The most common cause in backyard flocks is a vitamin deficiency, and the standard treatment is a combination of vitamin E, selenium, and B vitamins given daily until symptoms resolve.
What Causes Wry Neck
The list of possible causes is long, but vitamin deficiency tops it for backyard chickens. Vitamin E is the most frequent culprit. Chickens of all ages need between 10 and 25 IUs of vitamin E daily, and selenium is required for the body to absorb it properly. A deficiency in either one can trigger neurological symptoms, including the characteristic head twist.
Thiamine (vitamin B1) deficiency is the other major nutritional cause. The brain depends on thiamine to convert glucose into energy, so when levels drop, neurological problems appear quickly. Early signs include lethargy and head tremors. As the deficiency progresses, a chicken may sit on flexed legs and throw its head backward into a “stargazing” position. This happens because the muscles along the front of the neck become paralyzed. Without treatment, the bird eventually loses the ability to sit upright at all.
Beyond nutrition, wry neck can also result from head injuries, ear infections, lead toxicity, brain tumors, fungal infections, and serious viral diseases like Marek’s disease, Newcastle disease, and avian influenza. Newcastle disease, for example, causes twisted necks along with watery green diarrhea, tremors, respiratory distress, and high mortality in a flock. If multiple birds are showing neurological signs at the same time, or if you’re seeing sudden deaths alongside the wry neck, the cause is more likely infectious than nutritional, and you should contact a veterinarian.
How to Tell if It’s Nutritional
A nutritional case of wry neck typically affects a single bird rather than spreading through the flock. The chicken is otherwise alert, has no respiratory symptoms, no diarrhea, and no discharge from the eyes or nostrils. Silkies, Polish, and other crested breeds seem especially prone to it. Chicks and young pullets are more vulnerable than mature hens, though it can strike at any age.
If the bird was recently switched to a new feed, if the feed is old or improperly stored (heat and light destroy vitamin E), or if the diet relies heavily on soybean or lupin-based ingredients, a nutritional deficiency becomes even more likely. When in doubt, starting vitamin supplementation is a reasonable first step since it’s low-risk and the response is often visible within days.
The Vitamin Protocol
Treatment targets the three nutrients most associated with wry neck: vitamin E, selenium, and B-complex vitamins. Here’s what experienced poultry keepers use:
- Vitamin E: One 400 IU capsule given orally once a day. You can pierce the gel capsule and squeeze the oil directly into the bird’s beak.
- Selenium: 25 mcg once daily. Selenium tablets can be crushed and mixed into a small amount of feed or water. A simpler option is to offer a small piece of egg (selenium is naturally present in eggs), which also helps the vitamin E absorb.
- B vitamins: A poultry vitamin supplement or human B-complex supplement covering B1 (thiamine), B2, and B6. Dissolve it in the bird’s drinking water or administer it directly.
Give these supplements daily. Most poultry keepers report noticeable improvement within a few days to a week for mild cases, though severe cases can take two to three weeks or longer. Continue supplementation for at least a week after symptoms fully resolve.
One important note on thiamine: birds with a severe B1 deficiency often stop eating entirely and will not resume on their own. If your chicken refuses feed, you may need to force-feed the vitamins (using a syringe without a needle) before the bird will regain its appetite.
Supportive Care While the Bird Recovers
A chicken with wry neck can’t compete for food and water with the rest of the flock, and it’s vulnerable to being pecked or stepped on. Separate the bird into a quiet, sheltered space. A dog crate, a large plastic tub, or a small pen in a garage or shed works well. Keep bedding soft and the area warm, especially for chicks.
Hydration is critical. A bird that can’t hold its head upright will struggle to drink from a normal waterer. Use a small syringe or eyedropper to drip water along the side of the beak, letting the chicken swallow at its own pace. Go slowly. Forcing water too quickly risks aspiration into the lungs. Offer water several times throughout the day.
For feeding, a wet mash (regular feed mixed with water into a soft consistency) is easier for an affected bird to eat than dry crumble or pellets. Hold the dish at beak level, or gently guide the bird’s head toward the food. Some chickens with wry neck can eat if you steady their head for them. Others need to be syringe-fed a slurry of blended feed and water until the vitamins take effect.
Gentle Neck Exercises
While vitamins address the underlying deficiency, the muscles in the neck can stiffen or contract if the head stays in a twisted position for days. Several times a day, gently straighten the bird’s neck and hold it in a normal position for 15 to 30 seconds. Don’t force it or push past resistance. The goal is to maintain range of motion and prevent the muscles from locking into the abnormal posture permanently. Think of it less as physical therapy and more as a gentle stretch. Many keepers do this during each feeding and watering session so it becomes part of the routine.
When Treatment Isn’t Working
If you’ve been supplementing for two weeks with no improvement at all, the cause may not be nutritional. Head injuries can cause identical symptoms, and while mild trauma sometimes resolves on its own with rest, more serious injuries may not. Ear infections can also produce wry neck and require different treatment entirely.
Marek’s disease is the concern that worries most flock owners. It causes tumors on nerves and can produce wry neck along with paralysis of the legs or wings, weight loss, and irregular pupils. There is no treatment for Marek’s. If the bird is also showing leg paralysis, gray or irregularly shaped pupils, or progressive wasting, Marek’s becomes a stronger possibility.
Preventing Wry Neck in Your Flock
Store feed properly. Vitamin E degrades with heat, light, and time. Buy feed in quantities your flock will consume within a few weeks, and keep it in a cool, dry, sealed container. Check the mill date on the bag if one is printed.
A good-quality commercial poultry feed should provide adequate vitamins for most birds, but breeds prone to wry neck (Silkies and Polish especially) benefit from occasional supplementation. Adding a poultry vitamin and electrolyte mix to their water once or twice a week is a simple preventive measure. Offering foods naturally rich in vitamin E, like sunflower seeds, spinach, and broccoli, gives an extra nutritional buffer. Eggs and small amounts of fish provide natural selenium.
For chicks, make sure the starter feed is fresh and formulated for their age. Chicks grow rapidly and burn through their nutritional reserves fast, which is why wry neck often appears in the first few weeks of life.
