Well, the preliminary necropsy results just came in... poor Penny...
With her cancer, there is clearly nothing we could have done to help her, except for euthanizing her...
I feel very badly that she was in such a bad state, and especially so "emaciated"... in spite of our force feeding her, it seems she wasn't absorbing any of it and was really starving. Oddly, my other chicken's necropsy mentioned her crop and its contents, but there is no mention of Penny's crop being so full of liquid or anything else (maybe it had seeped out before they worked on her.) I was hoping to see that, because I thought perhaps her crop wasn't emptying because it was blocked by grass. Perhaps it was tumors that kept it from emptying, or maybe the intestines narrowed so much they were backing everything up. I might call the lab tomorrow to see if they can give me any info about this.
I'll work on understanding more of this tomorrow, but if anyone wants to comment, please do.

GROSS AND HISTOLOGIC DIAGNOSES: Ovarian cancer
1. Ovary and intestines: Metastatic adenocarcinoma
INCIDENTAL FINDINGS:
1. Liver: Vacuolar hepatopathy (hepatic lipidosis)
2. Lung: Fibrinous and heterophilic pneumonia

06/15/2022: There was gross and histologic evidence of ovarian carcinoma, which is the most frequent tumor of the reproductive system in chickens. Neoplastic cells are shed from tumors into the coelomic cavity. They implant on the ovary, pancreas, and other viscera and produce multiple, hard nodules. They may block lymph return (and result in ascites). Ovarian tumors usually don't become apparent until their growth is well advanced. (The bird may have a history of egg binding or oviduct prolapse. They may also have problems associated with egg laying, such as increased infections. ) The tumor in this case had metastasized to the lung, which may have contributed to the development of pneumonia. Lead testing is pending. An additional report is forthcoming.

(I wonder if the mention of pneumonia may have more to do with the liquid she aspirated that last night... I hadn't seen or heard any evidence of breathing issues until then.)

A 6-year-old Easter Egger hen (Penny) with a 1-month history of inappetence that died on 06/11/2022 is submitted for necropsy on 06/13/2022 in fair postmortem condition. The animal is emaciated. The liver is diffusely mottled tan to pale red and friable. The lungs are firm medially with dark red discoloration ventrally. The lungs partially sink in formalin. The coelomic serosa is markedly expanded by firm, white nodules throughout. The intestines are firmly adhered to one another with marked reduction in the luminal diameter. The oviduct has 3 x 0.5 cm discoid mass expanding the wall.

Ovary, liver, lung, and intestines are examined histologically. Ovary, lung, and intestines: Expanding the serosa of the intestines are lobules of neoplastic cells surrounded by a scirrhous response that variably form lobules. Similar cells are present within the lung, ovary and efface the pancreas. In the lung some cells have basilar oriented nuclei and eosinophilic apical cytoplasm.
