Wry Neck in Chickens: Causes and What to Do
TL;DR: Wry neck — a twisted or tilted head and neck a bird cannot correct — has several possible causes: vitamin E or selenium deficiency, physical injury, or a viral nervous system disease such as Newcastle Disease or Marek’s disease. A single bird with no other flock illness points toward a nutritional or injury cause; multiple sick birds or other signs like respiratory distress or paralysis point toward something viral and urgent. Supportive care (safe housing, hand-feeding, a vitamin E/selenium supplement per the label) helps nutritional cases; a vet exam is the only reliable way to know which you’re dealing with.
What Is Wry Neck?
Wry neck — also called crooked neck or torticollis — describes a twisted, tilted, or contorted position of a chicken’s head and neck that the bird cannot correct on its own. It’s a sign, not a diagnosis by itself: several genuinely different underlying problems can produce the same visible twist, which is why this guide focuses as much on telling the causes apart as on describing the twist itself.
That distinction matters more here than in most of the other conditions covered on this site, because one of the possible causes — Newcastle Disease — is a serious, no-cure viral disease where a twisted neck is the classic advanced-stage sign, while another possible cause — a vitamin deficiency — is manageable and often reversible with supportive care. Treating every case the same way risks either overreacting to a simple nutritional issue or underreacting to a genuine outbreak. See our guide to common chicken and gamefowl diseases for how wry neck’s possible causes fit alongside the flock’s other major health risks.
What Causes Wry Neck?
Vitamin E and selenium deficiency is one of the most common recognized nutritional causes, particularly in young, fast-growing birds on an incomplete diet, and it’s often manageable once identified. Physical injury or trauma to the head or neck — a fall, a collision, or rough handling — can also produce the same twisted appearance. On the more serious end, viral nervous system diseases, including Newcastle Disease and Marek’s disease, can cause wry neck as one of several neurological signs. An inner-ear problem affecting a bird’s sense of balance is another recognized, though less common, cause of a head tilt.
| Cause | Typical Pattern |
|---|---|
| Vitamin E / selenium deficiency | Often affects young, fast-growing birds; usually an isolated case, bird otherwise alert |
| Physical injury | Sudden onset after a fall, collision, or rough handling; usually one bird |
| Newcastle Disease (viral) | Can affect multiple birds; often accompanied by respiratory signs, diarrhea, or paralysis |
| Marek’s disease (viral) | A recognized cause of nervous system signs including head/neck tilt in poultry generally |
| Inner-ear/balance problem | Head tilt with balance difficulty, less common |
How Do You Tell a Simple Case From Something More Serious?
A single bird affected, otherwise alert, eating with help, and with no other sick birds in the flock leans toward a nutritional or injury cause — something you can reasonably support at home while watching closely. Multiple birds showing signs at the same time, or a bird also showing respiratory difficulty, greenish diarrhea, or paralysis alongside the neck twist, leans toward a viral cause and should be treated as urgent, including isolating the bird and watching the rest of the flock closely for the same signs. This distinction genuinely cannot be made with full confidence from observation alone — a veterinary exam is the only reliable way to know for certain, and that matters even more with Newcastle Disease specifically, since it’s a disease where isolating a suspected case fast changes the outcome for the rest of the flock.
If in doubt, treat it as the more serious possibility first. Isolating a bird with wry neck and watching the rest of the flock costs you little; missing an early Newcastle Disease case because you assumed it was nutritional can cost the whole flock.
How Do You Care for a Chicken With Wry Neck?
Keep the bird in a safe, padded, low-stimulation space where it can’t injure itself further by falling or struggling to move normally, and hand-feed and water it directly if it can’t manage well on its own — a bird with a severe head tilt often struggles to eat and drink normally, and dehydration or starvation can become the more immediate danger. A vitamin E and selenium-rich supplement, dosed per the product label, is commonly used to support a suspected nutritional case; this guide names the type of supplement rather than a specific brand or dose, since products vary and the label is the accurate source for that. If there’s any sign this could be viral rather than nutritional — other sick birds, respiratory signs, diarrhea, paralysis — isolate the bird immediately and treat it with the same urgency described in our Newcastle Disease guide.
| Step | What to Do |
|---|---|
| 1. Isolate | Move the bird to a safe, padded space away from hazards and, if any viral cause is possible, away from the rest of the flock |
| 2. Assist feeding and watering | Hand-feed and water directly if the bird cannot manage normally on its own |
| 3. Support nutritionally | A vitamin E/selenium-rich supplement, per the product label, is commonly used for a suspected nutritional case |
| 4. Watch the rest of the flock | Any other birds showing similar or additional signs shifts this toward a viral cause and changes the urgency |
| 5. Get a vet exam | The only reliable way to distinguish a nutritional case from a viral one |
How Do You Prevent Wry Neck?
A complete, balanced diet with adequate vitamin E and selenium is the main nutritional prevention step, and it’s worth reviewing your flock’s feeding program and vitamin and supplement routine if you’ve seen a nutritional case before. Reduce injury risk with sensible coop and perch design — covered in our farm and coop layout guide — and keep up with core vaccinations, including the Newcastle Disease vaccination schedule, since that addresses the most serious of the possible causes directly.
- Feed a complete, balanced diet with adequate vitamin E and selenium
- Reduce injury risk through sensible perch height and coop design
- Keep up with core vaccinations, especially Newcastle Disease
- Isolate and assess any bird with wry neck promptly rather than waiting to see if it resolves
What Are the Limits of This Guide?
This guide can describe the recognized causes of wry neck and the shape of supportive care, but it cannot tell you, from a description alone, which cause is behind a specific bird’s case. That distinction — especially ruling out a viral cause with real consequences for the rest of the flock — needs a hands-on veterinary exam. Treat any wry neck case as worth watching closely and, if there’s any doubt or any other bird shows signs of illness, worth a vet visit rather than a guess.

Frequently Asked Questions
What is wry neck in chickens?
Wry neck, also called crooked neck or torticollis, is a twisted or tilted position of the head and neck that a bird cannot correct on its own. It is a sign of an underlying problem rather than a disease by itself, and the underlying cause can range from mild and manageable to serious.
What causes wry neck in chickens?
Vitamin E or selenium deficiency, physical injury or trauma to the head or neck, and viral nervous system diseases such as Newcastle Disease or Marek's disease are the main recognized causes. An inner-ear problem affecting balance can also cause a head tilt.
Is wry neck the same as the twisted neck seen in Newcastle Disease?
Not always the same thing, but they can look identical from the outside. A twisted neck is the classic advanced-stage sign of Newcastle Disease, so any wry neck case should be checked against the rest of the flock for other Newcastle signs before assuming it is a simpler nutritional problem.
How do you tell if wry neck is nutritional or something more serious?
A single affected bird, otherwise alert and eating with help, with no other flock illness, points more toward a nutritional or injury cause. Multiple birds affected at once, or a bird also showing respiratory signs, diarrhea, or paralysis, points toward a viral cause and should be treated as urgent.
How do you care for a chicken with wry neck at home?
Keep the bird in a safe, padded, low-stress space to prevent further injury, and hand-feed and water it if it cannot manage on its own. A vitamin E and selenium-rich supplement, per the product label, is commonly used to support nutritional cases, but a vet exam is the only reliable way to confirm the cause.
Can wry neck be cured?
A nutritional or minor injury case often improves with supportive care and correcting the underlying deficiency. A case caused by a viral nervous system disease has a much less certain outlook, and that difference is exactly why identifying the cause matters rather than treating every case the same way.
How do you prevent wry neck in chickens?
A complete, balanced diet with adequate vitamin E and selenium is the main nutritional prevention step. Reducing injury risk in the coop and keeping up with core vaccinations, including for Newcastle Disease, address the other major causes.
