Soft tissue swelling, wing tip swelling (raptors), constrictive toe syndrome, pulmonary edema • Noninfectious causes: trauma (wing tip edema of raptors), fractures, feather cysts (especially in canaries) • Iatrogenic: tight bandages, surgical trauma • Coelomic mass effect: pulmonary edema • Cardiac disease (see Cardiac Disease) • Pulmonary edema: fluid overload, pulmonary disease, airborne toxins, obstruction of trachea, electrical shock • Infectious causes: viral diseases in poultry often cause swelling of the comb or wattles • Constrictive toe syndrome/constriction of toe by string foreign body: connective tissue circumferential bands restrict blood flow to distal toe, causing edema and swelling • Vitamin C deficiency in Ptarmigan and grouse chicks <4 weeks old causing skeletal muscle edema. • Neonatal edema Edematous chicks usually associated with high humidity, thick shell or inadequate ventilation during incubation; may result in external yolk sac upon hatch • Postavian circovirus infection syndrome, in which transudate to modified transudate occurs in the coelomic cavity. No treatment and the birds usually die or are euthanized.
