I had a necropsy done on my duck that showed the cause of death was egg yolk perontitis. A necropsy is a great way to find out the cause of death.Oh really ? Sorry to hear. Did you know what is was ? We still don’t know for sure and are all worried about our other duck
My duck wasn't showing the classic symptoms of egg yolk perontitis, and had come back with a positive avian malaria test so the vet thought she had that. Unfortunately anorexia is a symptom of many illnesses.
