After almost a decade of raising ducks, I had my first encounter with a condition called “angel wing” this past spring.
Fortunately, I had read about it years ago when we first started raising ducks and knew exactly what to do.
It then occurred to me that I should write an article about it for all my readers who raise ducks. This is a good one to bookmark or save on Pinterest, by the way, just in case….
Angel wing is a concerning condition that can affect ducks, causing their wings to twist outwards away from their body instead of lying flat. While not life-threatening it impairs a duck’s ability to fly and can lead to discomfort. The key to addressing angel wing is catching it early and taking prompt action. In this article, we’ll explore the early signs of angel wing to look out for, and how to treat it.
What is Angel Wing?
Angel wing, also known as airplane wing or slipped wing, causes the last joint of a duck’s wing to twist outwards instead of tucking neatly against their body This gives the wing a distinctive stuck-out appearance resembling an airplane’s wing, hence the name “angel wing”
It arises when the wing’s primary feathers grow faster than the wing muscles, bones, and ligaments can support. The heavy feathers exert pressure on the developing wing structure, causing it to twist out of place.
While more common in domesticated ducks, it can occur in any waterfowl including wild ducks, geese, and swans. Ducks are especially prone to developing angel wing between 8-12 weeks of age.
3 Early Signs of Angel Wing
Catching angel wing early is key, as it becomes a permanent deformity in mature ducks. Here are 3 early signs to watch for:
1. Drooping Wings
One of the first subtle symptoms of angel wing is the duck’s wings drooping lower than normal. Instead of being held snugly against the body, one or both wings will hang down more than usual.
2. Asymmetrical Wing Angles
As angel wing progresses, you may notice one wing sticks out more than the other. The affected wing will project outwards at an abnormal angle compared to the normal wing.
Mild cases have less than a 30-degree difference, moderate 30-60 degrees, and severe cases over 60 degrees.
3. Damaged Flight Feathers
Examine the primary flight feathers at the tip of the wings. If they appear twisted, bent, or otherwise abnormal, it can be indicative of improper growth caused by angel wing.
Damaged feathers impair the duck’s flying ability even before the joint deformity becomes noticeable.
What Causes Angel Wing?
The exact causes are debated, but these factors are thought to contribute:
-
High protein diet – Excess protein and calories during rapid growth spur overly fast development.
-
Confinement – Limited space and exercise hinder normal wing muscle growth.
-
Genetics – Some breeds are genetically predisposed.
-
Incubation issues – Improper temperature and humidity can impact development.
-
Rapid growth – Accelerated bone and muscle maturation increase deformity risks.
-
Metabolic disorders – Nutrient absorption issues can disrupt growth regulation.
Treating Angel Wing in Young Ducks
The good news is angel wing can often be corrected in young, growing ducks through a combination of dietary changes, physical therapy, and taping the wing in the proper position. Here are 5 tips for treatment:
1. Transition to a Lower Protein Diet
Switch young ducks showing signs to a feed containing a maximum of 16% protein to slow growth. Avoid high carb foods like bread.
2. Add Alfalfa Pellets
Alfalfa is thought to aid in realigning bone growth. Provide a small dish for free choice consumption.
3. Wrap the Wing
Gently tape the affected wing against the body using vet wrap or bandages. Change weekly.
4. Massage and Stretch
Gently massage and stretch wings to encourage proper muscle growth and flexibility.
5. Patience!
Improvement happens gradually. Monitor often and adjust treatment as needed until the wing corrects.
Preventing Angel Wing in Ducklings
Prevention starts with proper nutrition and rearing methods:
-
Feed a quality 18% protein starter for only the first 2 weeks, then transition to 15-16% grower feed.
-
Allow access to greens, vegetables, and bugs for natural foraging.
-
Provide ample space and swimming opportunities to exercise wings.
-
Avoid overcrowding, stress, and rapid growth spurts.
-
Select breeds with lower susceptibility and breed for proper wing strength.
When to Seek Veterinary Help
If angel wing persists despite home treatment, or if you notice it in older ducks, seek input from an avian vet. They can provide nutritional guidance, physical therapy, and taping advice tailored to your duck’s needs.
While angel wing can’t be reversed in mature ducks, vets can help manage pain and prevent worsening. Don’t hesitate to enlist their expertise.
The Earlier the Better!
Catching angel wing early and taking prompt action provides ducklings their best chance at recovery. By knowing the subtle early signs, making dietary adjustments, and taping the wing before permanent deformity sets in, ducks can go on to live normal, healthy lives.
With attentive monitoring and care from their caretakers, most affected ducks fully recover from this condition. Don’t wait – if you suspect angel wing, address it right away for optimal results!
What is Angel Wing?
Angel wing (sometimes referred to airplane, twisted or crooked wing) is a cosmetic condition that ducks can be afflicted with that causes the flight feathers on the tip of a ducks wing to twist or rotate as they grow and the feathers to point away from the body, instead of laying flat.
When the feathers grow faster than the ducks wing structure, the heavy feathers cause the last joint of the wing to twist out away from the ducks body.
Once the bird matures, the affected wing permanently sticks out at an awkward angle instead of gracefully folding against the body.
Ducklings between 8 to 12 weeks of age are most at risk, with ducks over 16 weeks having matured enough – and their wing bones fully formed – that it wont occur in them.
Inexplicably, it usually occurs just on the left wing or both wings (leading to the appearance of angel wings, hence the name), rarely occurring in the right wing alone.
And sure enough, it showed up in our Black Swedish duckling, Olive, on just her left wing when she was just a few weeks old. It also showed up in our Blue Swedish duckling, Fig.
What Causes Angel Wing?
Although several studies have pointed to Angel Wing as being genetic or resulting from incorrect incubator temperature, most researchers and duck experts feel that it is the result of excess protein in the ducklings diet.
Feeding ducklings a diet too high in protein/energy causes them to grow too fast, and the weight of their wings ends up being greater than the strength of the wing to support itself. This is what causes the twisting at the very tip of the wing.

FAQ
What are the early signs of angel wing in ducks?
The result is a wrist which is twisted outwards and unable to perform its usual function. Angel wing symptoms include stripped remiges (flight feathers) in the wrist area, or remiges protruding from wings at odd angles. In extreme cases, the stripped feathers may resemble sickly blue straw protruding from wings.
What does the start of angel wing look like?
Angel Wing is a condition that affects waterfowl, such as Trumpeter Swans. The condition causes the last joint of the wing (carpus/wrist) to twist making their primary flight feathers point laterally outwards. This abnormality prevents the feathers from laying flat against the body.
Is angel wing a birth defect?
Angel wing is caused by a nutritional deficiency and does not spread from affected animals to unaffected animals. The only way that birds acquire it is from a diet that lacks certain vitamins and nutrients critical to their development.
How do I know if my angel wings are drooping?
Drooping Wings: One of the early signs. You might notice their wings aren’t tightly held against their body like the way they should be. Instead, one or both of the wings may hang down lower than usual. Wing Angle: This symptom will be shown in more severe conditions of angel wings.
How do you know if a duck has angel wings?
Instead, one or both of the wings may hang down lower than usual. Wing Angle: This symptom will be shown in more severe conditions of angel wings. The wings can stick out at an angle greater than 60 degrees for your duck’s body. This might look like they’re forming a V shape. Damaged Feather: Sometimes, the primary feathers might be damaged.
Why do ducks have angel wings?
Angel wings in ducks can be called a certain feather condition. It’s like when the feathers in their wings stand out instead of lying flat like normal. It makes the wings look twisted and will affect the flying ability of a duck. Read more Can Ducks Eat Coconut? Yes, As An Occasional Treat!
When do Ducks develop Angel Wing?
However, if treatment is postponed or the condition goes unnoticed until the duck reaches maturity, the deformity becomes permanent. Ducks are particularly susceptible to developing angel wing between 8 to 12 weeks of age. A Muscovy Duck with Angel Wing from CC BY-SA 3.0
How do you treat angel wing?
If signs of angel wing are caught early enough, while the bird is still young and their bones are still flexible, treatment can be attempted through an immediate change of diet and wrapping the wing against the body to keep it untwisted until the bones strengthen.
How severe are angel wings?
A group of researchers from Taiwan have measured these severity levels of angel wings. Let’s take a look. Grade 1 (Slight): The primary feathers stick out from the body at less than a 30-degree angle. This is just a minor case. Grade 2 (Moderate): The feathers project out at an angle of 30 to 60 degrees from the body.
