Angel Wing

) in the wrist area, or remiges protruding from wings at odd angles. In extreme cases, the stripped feathers may resemble sickly blue straw protruding from wings. In adult birds the disease is incurable and usually leads to an early death as affected birds are rendered effectively or totally flightless. In young birds wrapping the wing and binding it against the bird's flank, together with feeding the bird a more natural diet, can reverse the damage.

There are currently two basic theories concerning the cause of Angel Wing:

#The first involves too much protein and the second involves too many sugars. Angel Wing is not generally observed in waterfowl not residing near humans, and the disease can often be observed in areas where geese or ducks are excessively fed bread. To prevent Angel Wing, waterfowl should not be fed bread, popcorn or other human foodstuffs. Duck seed is an alternative for duck feeders.
#The second theory is that the cause could be genetic, as the same breeding pair can produce several Angel Wing chicks or cygnets over many broods.

As little research has been done on this, it is impossible to favour one theory over the other.
