Miss Adzuki Bean’s Case Of Egg Yolk Peritonitis

Miss Adzuki is a two-year old Golden Laced Wyandotte. She lives in an urban backyard environment in Oakland, California with five other hens as part of the ‘Bean Team’. The other members of the 'Bean Team' include Lentil, Fava, Jellybean, Kopi (which means coffee in Indonesian), and Cannellini Molasses-face). The flock of sweet hens are kept in a large predator-proofed enclosure outside, within a fenced in backyard. The enclosure contains a chicken coop for them to sleep in at night and to lay eggs in built in nestboxes during the day. Whenever one of their owners, Alex Witte and Zac Diener are home, they let the girls explore the remainder of their fenced in backyard to scratch and forage in the garden.

Clinical Signs of an Egg-Related Problem

One morning, when Alex was in the coop feeding the girls their breakfast, she came across a yolk and white material from what would usually be inside an egg, on the ground without any egg shell material in sight (otherwise known as a shell-less egg). Alex started throwing out some freeze-dried mealworms for the birds in the garden. Most of the hens would intensely chase after the worms just as they normally would, however Adzuki ate one or two and then just stood in place, uninterested in going after any more worms. The rest of the birds were running around like crazy after the remainder of available worms. A few hours later, Alex looked in on the girls and noticed Adzuki sitting in the nestbox, panting really hard with her beak open. However, it wasn’t hot out and the other hens weren’t panting.

Alex suspected that perhaps Adzuki was egg bound, and she and Zac brought her inside the house and gave her a warm bath to try to see whether that might help relax her into laying the egg. Several minutes went by and Adzuki started to look like she was falling asleep, and started acting very lethargic. Alex removed her from the bath and gently placed her inside a shallow cardboard box lined with a blanket, with easy access to a small dish of water and feed (which Adzuki never touched). While Alex was tending to Adzuki, Zac called up Montclair Veterinary Clinic and scheduled an emergency appointment for Adzuki to be examined by a veterinarian. After Zac described to the receptionist the signs Adzuki had presented with, the clinic agreed that she needed immediate medical attention and scheduled her in to see a doctor that same afternoon.

Adzuki’s Vet Visit

Dr. Justin Cupka greeted Zac and Adzuki in one of the examination rooms at the veterinary hospital. He gave Adzuki a physical exam and palpated her abdomen to see if he could feel the presence of an egg. He didn’t feel anything there, however that didn’t mean there wasn’t an egg present---for soft-shelled and shell-less eggs often aren’t detectable through palpation. Dr. Cupka then recommended an ultrasound, for it can be useful for helping to identify the presence of many types of egg abnormalities that are not recognizable in radiographs, including thin-shelled, malformed, and shell-less eggs. Adzuki’s ultrasound didn’t reveal any significant findings. Since Adzuki had not been eating or drinking on her own, she had become dehydrated, so the doctor administered subcutaneous fluids and a Vitamin B12 injection (1000 mcg/mL).

Based on her history, clinical signs, physical exam, and absence of relevant findings from the ultrasound, the doctor concluded Adzuki had egg yolk peritonitis. Due to her lack of appetite and reduced intake of water, he advised that her prognosis for recovery was not good. Dr. Cupka prescribed Enrofloxacin (Baytril), 20 mg/ml which is a type of antibiotic, to be administered to her orally by mouth twice a day, for four days. Dr. Cupka also brought up his concern about the abnormal eggs Adzuki laid---since egg yolk peritonitis is caused by the presence of rotting egg material inside the hen. He suggested that if Adzuki recovered, that Zac and Alex should probably consider spaying her----as a means of preventing future egg-related infections.

Adzuki’s Road to Recovery

While Adzuki was recovering and receiving her antibiotics, she was kept inside the house with Alex and Zac. They put together a chicken ‘sickbay’ for her, using a 2’x4’ plywood box layered with blankets that was placed inside their office room, so they could keep a close eye on her. They provided a small bowl of fresh water and feed positioned so that Adzuki had easy access, to promote her eating and drinking.

For some additional supportive care and enrichment, Adzuki was pampered with regular all-star spa sessions (warm baths and blow dries) and cuddles. Adzuki’s appetite slowly returned to normal and she started drinking again. Once Adzuki finished her course of antibiotics, and Alex and Zac were convinced she was feeling better, they returned her to live back outside with her feathered friends. They are looking into different treatment methods available to stop Adzuki from laying eggs, and planning to discuss the use of hormone implants with Dr. Cupka---for they don't care about the eggs and would rather Adzuki be alive and happy.
