Presenting problem: Cloacal Prolapse in Birds

Cloacal prolapse is a serious and potentially life-threatening problem. Prolapses can originate from the cloaca, oviduct or intestinal tract. The cloaca normally prolapses during egg laying or oviposition, and normal retraction of the cloaca may be slowed or absent in an obese hen or one with hypocalcemia. Excessive abdominal contractions caused by an abnormal egg, dystocia, cloacal disease, gastrointestinal disease or chronic mastubatory behavior can also promote prolapse.
