Egg yolk peritonitis is considered to be a life-threatening emergency for hens. It occurs commonly in sexually mature laying hens, especially breeds that were created for excessive egg production--such as the Leghorn, Sex link (including the Black Star and Red Star), and ISA Brown Sex link. Egg yolk peritonitis is defined as the presence of yolk material in the peritoneum (the thin tissue lining the inner wall of the abdomen) and celomic cavity of the hen. The presence of the yolk material causes an inflammatory response and often gets reabsorbed by the peritoneum. However, since yolk is an excellent growth medium for bacteria, peritonitis often occurs as a result of a secondary bacterial infection. The infection causes a localized to diffuse fibrinous reaction which may also lead to the onset of ascites, inflammation of multiple organs, and result in organ compromise. Egg yolk peritonitis can also develop secondary to hens silently suffering from salpingitis. Affected hens may have a history of egg binding, usually within the past six months.
Isolate the bird from the flock and place in a safe, comfortable, warm location (your own chicken "intensive care unit") with easy access to water and food. Limit stress. Call your veterinarian.
Most hens require surgery to remove the accumulated egg material from their body and infected or atrophied parts of the hen's reproductive system. Essentially she will need to be 'spayed', followed by a course of antibiotics.
