I think my muscovies are developing angel wing. I have raised many other breeds of ducks and have never had this problem. 2 out of the 4 (from the same hatching) are developing it. Is this a genetic trait? Also, what is the best way to fix it? They are rather large and stay outside, so I'm not sure if taping them would help. Thanks! Its mostly the blue one in the middle. Both of his wings drag on the ground. The wings don't point outwards, they just sag. And the blue and white one on the left has developed the same thing on his right wing. I'm not sure if this is considered angel wing or not, but any help would be greatly appreciated!
