I have been wondering if Angel Wing is genetic or Nutritional. I at first thought it was nutritional. I had a really pretty Muscovy drake with Angel wing given to me. I used him and none of the babies were deformed. However, I have been wondering if it is genetic? I got ducks from Holdereads and one of them has angel wing. I figured if I complained he would say it was because of my feeding program. However I have never before had any bird develop angelwing on this farm until this year. One Mallard from a hatchery and one of Holdereads ducks have it. The hatchery one I am not surprised. I was a little surprised that the one from Dave Holderead had it. Our feed has not changed only different ducks. Any help would be greatly appreciated.
