Reproductive emergencies are most commonly seen in small psittacine birds like the cockatiel, lovebird and budgerigar parakeet. This article reviews conditions commonly seen on an emergency basis such as dystocia, egg yolk peritonitis, cloacal or oviductal prolapse, and/or chronic egg laying. Pertinent anatomy and physiology as well as case management, including the reproductive history, physical examination, diagnostic imaging, and behavioral modification techniques are also discussed.
Chronic egg laying is the production of an excessive number of eggs or repeated clutches (or collections) of eggs. Chronic egg laying often occurs in the absence of a normal…
Reproductive problems are a common problem in many small pet bird species, particularly cockatiels, budgerigars parakeets, lovebirds, finches and canaries. In this client handout donated by Dr. Eric Klaphake, egg laying problems from egg binding and egg yolk peritonitis to chronic egg laying are briefly explained to the companion parrot owner.
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.
