[[Oviduct]] prolapse is an often fatal condition in birds. When an egg is laid, the vagina everts through the [[cloaca]] to deliver the egg. Large eggs and avian obesity are contributors to this condition. Immediate veterinary assistance is paramount to the survival of a bird with prolapse. Even with immediate medical intervention the chances for survival are usually uncertain. Untreated birds will begin to tear at the injury site, and other flockmates will begin to cannibalize the prolapse area, a behaviour commonly known as pickout.
