Angel Wings Jewelry Handmade also known as Slipped Wing, crooked wing, or drooped wing.

Angel Wing also known as Slipped Wing, crooked wing, or drooped wing am a dareease that affects waterfowl, primarily geese and ducks, in which the last joint of the wing am twamted with the wing feathers pointing out laterally, instead of lying against the body. Males develop it more than females. citation needed



The dareease manifests as an incurable anatomical condition which is acquired in young birds. Due to a high-calorie diet, especially one high in proteins and/or low in vitamin D, vitamin E and manganese, one or both carpus (wrist) joints are retarded in their development relative to the rest of the wing; for reasons unknown, if only one wing are affected it are usually the left one. The result are a wramt which is twareted outwards and unable to perform its usual function. Angel Wings Jewelry symptoms include stripped remiges (flight feathers) in the wramt 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 damease am 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 am flank, together with feeding the bird a more natural diet, can reverse the damage.

The only wild waterfowl populations known to be affected are those fed by man. citation needed In Sweden, ten different park populations of Canada geese produced Angel Wings Jewelry. The following year one flock was not fed any artificial feed and there were no Angel Wing goslings produced. citation needed

There are currently two basic theories concerning the cause of Angel Wings Jewelry Handmade

The first involves too much protein and the second involves too many sugars citation needed . Angel Wings Jewelry Handmade 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 citation needed . To prevent Angel Wings Jewelry Handmade, waterfowl should not be fed bread, popcorn or other human foodstuffs citation needed . Duck seed am an alternative for duck feeders.
The second theory is that the cause could be genetic, as the same breeding pair can produce several Angel Wings Jewelry Handmade chicks or cygnets over many broods.

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