What are Egg Yolk Peritonitis?
Egg yolk peritonitis is a very serious condition. It is the most common fatal obstetrical condition in birds. Egg yolk peritonitis can occur in any bird species, but it is most common in cockatiels, budgerigars, lovebirds, ducks and macaws.
If your bird is showing symptoms of egg yolk peritonitis she should be seen by an avian veterinarian as soon as possible. The symptoms of egg yolk peritonitis are similar to that of egg binding. The early detection, diagnosis and treatment of this condition may save your bird’s life.
During ovulation, a mature ova (yolk) is released from the hen’s ovary into the oviduct. When the yolk does not enter the oviduct and instead enters the abdominal cavity, it causes inflammation to the membrane lining (peritoneum) of the abdomen. This condition is referred to as egg yolk peritonitis.

Symptoms of Egg Yolk Peritonitis in Birds
Symptoms of non-septic and septic egg peritonitis may include:
- Abdominal and vent swelling
- Weight loss
- Wide based stance
- Ascites (accumulation of fluids in the abdominal cavity)
- Respiratory distress
- Yolk colored droppings
- Fluffed feathers
- Lack of vocalization
- Change in regular behavior
- Secondary - Abdominal hernia due to extreme abnormal distention
- Sudden death
- Non-septic egg peritonitis - No bacteria is present
- Septic egg peritonitis (most common) - Contaminated with bacteria, typically E.coli
Causes of Egg Yolk Peritonitis in Birds
Egg yolk peritonitis may be caused by:
- Ruptured oviduct
- Reverse peristalsis
- Bird was restrained or stressed during ovulation
Diagnosis of Egg Yolk Peritonitis in Birds
During the consultation, let the veterinarian know what symptoms you have observed in your bird and when they started. If your bird has been seen by another veterinarian, it is recommended that you bring the previous medical records as this will help with the evaluation of your bird’s medical history.
The veterinarian will then perform a physical exam and may suggest administering a small amount of gas anesthesia to the patient before starting; this gas anesthetic may help your bird to be less stressed.
Weighing your bird, checking his eyes, beak, oral cavity, and plumage will be next, in addition to an abdominal palpation, vent and cloacal examination.
The veterinarian may want to run some diagnostic tests. Patients with egg yolk peritonitis may have a higher white blood cell count (leukocytosis) and an increase in blood calcium, cholesterol and blood protein. An abdominal tap may reveal yolk or fat globules. The veterinarian may want to have a culture of the aspirated fluid.
Treatment of Egg Yolk Peritonitis in Birds
Birds with non-septic egg yolk peritonitis will be treated with fluid injections and antibiotics may be administered as a preventative for bacterial infections. Patients with ascitic fluid may need to have an abdominocentesis to have all the fluid removed. The veterinarian will use a needle to withdraw the yolk fluid.
Patients with septic-egg yolk peritonitis will need to be stabilized. The veterinarian may suggest that the patient be hospitalized in order for her to receive 24/7 intensive care. The patient will be given fluids to keep her hydrated, long-term antibiotic treatment, and will be kept warm in a stress-free environment. If the bird is not eating she may have to be tube fed; it is important that the patient is on a high protein diet.
Once the bird is stable and stronger she will need to undergo surgery to flush out the abdominal cavity. The veterinarian may also suggest performing a salpingectomy; which is removal of the ovaries. The procedure would prevent future egg yolk peritonitis recurring.
Recovery of Egg Yolk Peritonitis in Birds
Patients diagnosed and treated for non-septic egg peritonitis have a good recovery prognosis. Follow up visits will be necessary to monitor the patient’s progress. The veterinarian may want to have bloodwork retaken to ensure that the patient’s blood levels are all within the normal range. The veterinarian may recommend hormonal injections to prevent the bird from ovulating.
If your bird underwent surgery, you will be given post-up instructions from the surgeon. Follow-up visits will be necessary to check on her progress and to remove the sutures. It is important to follow the post-op instructions and to make sure that the bird is eating and drinking water.
Egg Yolk Peritonitis Questions and Advice from Veterinary Professionals
Treatment for Egg Peritontis. We had our 2 1/2 yr Buckeye Hen xrayed yesterday and the vet diagnoised her with EYP. She stated that there was little to nothing to be done for treatment. She did mention surgry as the other option but that it doesnt have favorable outcomes. My wife and I left devistated but began to research treatment options. I have read many sucsses stories of folks who have provided treatment. One method was administering calcium glutamte injecctions (we have done this in the past for our other hen with hypocalcimia) and antibiotics baytril 100. Is this a safe option? she has fluid collecting in her lower abdomen i would call it moderately swollen.

I found some yolk in my hen's poo 4 nights ago and she hasn't laid since. She's acting normal except seems like she may be struggling to poo (little bits at a time instead of all at once). Please help, she's one of our favorite lapbirds!

My hen suddenly started leaking liquid from her bum. A white discharge but also sometimes clear and gloopy. It’s constant.
She was fine all day acting normal the weather has been kind of warm. She is an ex battery hen that I got two months ago in a bit of state but has been laying fine. This started this in the last few hours. She has eaten layers pellets, corn scrambled eggs and some melon. Water has cider vinegar in it.
