My ducks are 4 months old now. Both wings on my Cayuga are effected and one wing on my Blue Swedish. I'm new to having ducks and thought they were just awkwardly growing, even looked up the funky wings on the internet and nothing came up until recently I figured out it was "Angel Wing". They came out of an assorted domestic bunch at a hatchery, I don't know if that has anything to do with it. I have read their diet has a lot to do with it but I don't think that's the case with these two. Anyway, is it too late to fix this? I've only seen people fix it on babies but mine are pretty large now. Also if it is fixable I'd like some input on how to go about it. Thank you all! Hoping for some quick replies.
