Twisted Neck (Torticollis) in Geese: Neurologic and Injury Causes

Twisted neck, also called torticollis, describes an abnormal head and neck position where a goose may hold the neck bent, tilted, rotated, or even arched backward. It is a clinical sign, not a disease by itself. In geese and other waterfowl, torticollis usually points to a problem affecting the brain, inner ear balance system, neck muscles, or cervical spine. Merck notes that nutritional neurologic disease such as vitamin E deficiency can cause ataxia and cerebellar damage in poultry, while Cornell also lists torticollis among neurologic signs seen in avian influenza survivors.

In geese, the most common broad categories are injury, nutrition-related neurologic disease, toxins, and infection. A goose that struck fencing, was grabbed by a predator, or was stepped on can develop pain, swelling, or spinal injury. Others may show a twisted neck because of vitamin deficiency, especially if the diet is unbalanced, rancid, or not formulated for waterfowl. Waterfowl are also vulnerable to botulism, which causes progressive weakness and neck paralysis often called limberneck. (merckvetmanual.com)

Because some infectious causes can affect the whole flock and may require reporting, a goose with torticollis should be treated as urgent until your vet says otherwise. Fast assessment helps protect both the sick bird and the rest of your birds.

One major group of causes is neurologic disease. In poultry, severe vitamin E deficiency can cause encephalomalacia, a brain disorder associated with ataxia and cerebellar damage. Merck notes that ducks and geese need adequate vitamin E in feed and that early supplementation may help some deficiency-related cases, depending on how much damage has already occurred. Selenium status also interacts with vitamin E in antioxidant protection. (merckvetmanual.com)

Another common category is injury. A goose may develop torticollis after collision trauma, predator attack, rough handling, entanglement, or neck strain. In these cases, pain, swelling, bruising, inner ear injury, or cervical vertebral damage may all contribute. Trauma can look similar to neurologic disease at first, which is why a hands-on exam matters.

Toxins and toxic infections are also important in waterfowl. Botulism is especially relevant because it commonly affects waterfowl and causes progressive weakness with neck paralysis, often called limberneck. Exposure is often linked to decaying organic matter, maggots, stagnant water, or carcasses. Other toxic exposures can also affect the nervous system, including some plants, chemicals, and heavy metals. (merckvetmanual.com)

Finally, infectious disease must stay on the list. Cornell reports that birds surviving avian influenza may show neurologic signs such as torticollis, opisthotonos, incoordination, and paralysis. If a goose with a twisted neck also has respiratory signs, diarrhea, sudden drop in activity, or flockmates that are ill or dying, your vet may need to consider reportable poultry disease and guide testing and isolation.

Diagnosis starts with a careful history and physical exam. Your vet will want to know the goose’s age, diet, access to ponds or spoiled material, recent trauma, new birds, wild bird exposure, and whether any flockmates are showing weakness, respiratory signs, or sudden death. That history helps separate likely trauma from nutritional, toxic, or infectious causes.

The exam usually focuses on neurologic status, hydration, body condition, and evidence of injury. Your vet may check whether the neck is painful or floppy, whether the bird can swallow safely, and whether there are signs of wing or leg weakness. If trauma is possible, radiographs can help look for fractures or cervical injury. If nutritional disease is suspected, your vet may review the feed, storage conditions, and any supplements being used. In flock cases, necropsy and feed review can be very helpful.

Additional testing depends on the situation. A stable goose may need bloodwork, fecal testing, or imaging. A severely affected bird may need supportive care first. If botulism is suspected, diagnosis is often based on clinical signs and exposure history, because toxin detection can be difficult. If avian influenza or another serious flock disease is on the list, your vet may recommend immediate isolation and official testing through animal health channels. (merckvetmanual.com)

Prevention starts with nutrition and feed handling. Feed a balanced ration formulated for geese or waterfowl life stage, store feed in a cool dry place, and replace stale or rancid feed promptly. Merck notes that adequate stabilized vitamin E and selenium are important in preventing deficiency-related disease in poultry, especially when diets contain unstable fats. Avoid improvising long-term diets with mostly scratch grains, bread, or kitchen scraps. (merckvetmanual.com)

Next, reduce injury risk. Keep fencing visible and safe, remove entanglement hazards, supervise introductions, and protect geese from predator attacks and rough handling. Weak or recovering birds should not have access to deep water if they cannot hold their heads up reliably.

Finally, use strong biosecurity and environmental hygiene. Cornell advises biosecurity around waterfowl because avian influenza viruses are carried by wild aquatic birds and can spread through saliva, mucus, and feces. Clean up spilled feed, limit standing water that attracts wild birds, cover feed, and keep domestic geese away from sick or dead wild birds. Remove carcasses and decaying organic matter quickly to lower botulism risk in wet areas. (cwhl.vet.cornell.edu)
