I've noticed a lot of discussion about angel wing in ducks lately and after having just dealt with it for the first time myself, I wanted to try to help others if possible. Now let me reiterate that I've only dealt with it just recently in two of my ducklings. I did not invent the method, but was instead following this video. It is also not the only way of dealing with it since every duck and owner are different, and what works for one person might not work for another. Still, if there are any questions and/or suggestions, feel free to post them. Sharing your experiences here may help others who are looking for answers! What Is Angel Wing? Angel wing is essentially when the flight feathers of the young bird develop faster than the muscles that usually hold them up. When the muscles can't take the sudden weight, the wing droops, causing the carpal bones to twist outward. This can then become permanent if not treated properly. It is not a death sentence, but it does prevent them from ever flying, and poses a high risk of catching on things. It's simple to fix, so there's no reason not to. What Causes It? All we have are theories at this point. The most common is that a diet too high in protein is to blame, causing them to grow too quickly. Another possibility is genetics. What we do know is that it seems to afflict the left wing the most. P.S. My apologies on the poor video quality! My sister was kind enough to record it using her phone and I had to edit out sections where my ducklings decided that they no longer wanted to be involved, evidenced by my Saxony stress panting at the end. Maybe someday I'll redo it.
