Egg binding (dystocia)
Also known as: Egg bound
Egg binding is the failure of a female bird to pass a formed egg through the oviduct and vent within the normal time. It is a potentially life-threatening emergency caused by oversized or malformed eggs, calcium deficiency, oviduct dysfunction or obesity. Retained eggs can cause straining, prolapse, peritonitis and death.
