I see you're in San Diego? The Dr. wanted to know what age and what breed, so that's why I asked.

She was a Splash Andalusian, yes, in San Diego county. She came from a hatchery, I'm not sure which one because I got her from someone else who had ordered many chicks. I have no others left from that group of pullets I got (sold/rehomed long ago). She was probably about 3.5 years old, the second oldest chicken in my flock. The oldest (about 4 yrs old) is still fine, and is laying regularly. I have never lost a chicken to anything like that before - only 2 to sour crop in 4 years of raising chickens.

I'm guessing ovarian adenocarcinomas(cancer)based on grape like clusters and the fact they were heavily interlaced with connective tissue,were clusters filled with yellow fluid?

I agree, and each of the "bubbles" had veins going to them. Some of them broke as I was trying to pull out all the innards to examine - I had to yank quite hard to get what I could out. What was inside of them was a clearish/bloodyish thin fluid.
 
I mostly deal with dogs and cats, but it looks identical to ovarian cysts that we have removed from dogs. Im so sorry.

This is really interesting, I'm surprised there aren't more responses! I'm new to chickens, ducks, etc., but I do have extensive knowledge in the medical field. Unfortunately, this seems like a textbook case of cystic echinococcosis. What you're looking at is cysts, but more specifically it's eggs... This is a very tricky thing to treat. The echinococcosis parasite(type of tape worm) only lives in carnivorous mammals definitively, but is passed through the feces into water, soil, etc., and enters the intermediate host this way. The intermediate host can really take the form of any wild herbivore. It is likely the chicken was infected through it's water or food, and regretfully that means that the rest of your chickens are likely infected as well. This is a difficult thing to cure, or prevent for that matter. I can only suggest to take your chickens to the vet and they will do an ultrasound and decide what to do from there.. I would also recommend you take yourself to the doctors, just to be safe. I don't know of you grow your own vegetables or eat your chicken's eggs, but there's a chance you could have it as well. This disease is quite common on farms.

I just showed this picture to a pathologist, and he agreed with you on the echinococcus. He has seen the grape-like clusters on human livers before, and it has shown up in stool samples in his lab. good job IDing this necropsy picture.
 
Those pics are certainly gross, Kathy.

There was someone who posted the same thing a few years ago. And I don't know if they ever found out what was wrong.

I had a hen die 4 years ago, my first necropsy, and I found that but much less. I didn't know what to think. They were attached all over . On her final days her poo smelled sooooo bad.
 
It is definitely cancer. I had a necropsy performed on one of my 3 year old hens last spring by an avian veterinarian. My hen looked exactly like your pictures.

An avian vet or avian pathologist? And did they send samples of for testing to determine what type of cancer?
