I'm sorry, I know there are so many questions about specific ducks and angel wing but it's so hard to tell what is abnormal wings vs normal feather growth and I'm freaking out. Just noticed a few of my 4 week old khaki Campbell's and Pekins wings look a bit odd. I have them on 16% protein feed and thought I was giving them plenty of niacin in Brewer'sYeast, but just checked the container and the label doesn't mention any niacin at all! Any help you could give in diagnosis would be much appreciated.
