let him try to play through a week if not better tape him, regardless of what you heard on what causes angelwing I would cut down on your protien in your bagged food. i do not know if you supplement your ducks with greens,grass,peas,etc. but this is 100% fact If you have them in a bare pen with no grass or other greenery and you give them high protien ration you will get some angelwing in some of your birds. FACT. BUT if you are able to free range them or give them other veggies you may or may not get it with high protien. so yes high protien does cause angelwing! If you dont want to wait a week with low protien food go ahead and tape him now Good Luck
