Two hens died and we found out why

Like most others here, I have experienced unexplained deaths of my hens. I lost two of them this week, which has been very sad for us, but at least this time I found out why.

Vet care and necropsies can be prohibitively expensive so very often one never knows why a hen dies, but we were very anxious to know what was wrong with our birds. I hope this information can help others:
Our vet told us the cost was $170 for the UCD necropsy. It didn't go to Davis but to someplace in San Bernardino.

It's one of the four labs that do the free necropsy.

Lab Locations

CAHFS is a livestock and avian diagnostic laboratory, not a small animal laboratory. Questions concerning dogs, cats, snakes, and fish should be directed to your local veterinarian.
The CAHFS Toxicology Section may be contacted regarding any poisoning cases in all animal species at this number: (530) 752-6322.
Each laboratory in the CAHFS System performs specific tests. If the CAHFS Lab nearest your location does not perform the test(s) needed for your submission, the specimen may be forwarded to the lab in the CAHFS System that does perform the test.
Business Hours: Monday through Friday, 8 AM to 5 PM
Emergencies only on Saturday and Sunday.


Davis Laboratory

The Davis facility consists of two laboratory buildings: The John E. Thurman, Jr. Building, and the Kenneth L. Maddy building. Davis is staffed and equipped to provide the full range of diagnostic procedures in the disciplines of pathology, bacteriology, mycology, serology, avian virology, mammalian virology and toxicology for all species of livestock including poultry. It also houses the Equine Analytical Chemistry laboratory, which is staffed and equipped to provide equine drug testing.
The Davis laboratory also conducts tests on specimens forwarded from the other four laboratories, which have not been staffed and equipped to perform them. As the central laboratory of the CAHFS, it provides professional support and supervision of tests and procedures to be used throughout the CAHFS. Discipline specialists at Davis, working with diagnosticians at the other laboratories, develop standard protocols and provide standardized reagents for use in the CAHFS. They also have supervisory responsibility over activities of their specialty, including both monitoring of testing procedures and the training of personnel in the use of such procedures at the other laboratories.
The Davis Laboratory accepts AVIAN, LIVESTOCK, and HORSE submissions. Carcasses may be submitted for necropsy. Submissions for livestock and horse biopsies, serology, bacterial cultures and electron microscopy are also accepted. The Toxicology section of the Davis Lab will accept specimens from all animal species, including domestic animals, wildlife, and sea mammals.

Turlock Laboratory

The Turlock laboratory provides diagnostic support for the needs of the poultry industry in the northern San Joaquin valley. It provides diagnostic services in pathology, bacteriology, serology, mycology, and in some aspects of virology. The Turlock Laboratory serves as a point of access to the CAHFS and all of its services except necropsies of large animals. Specimens (except large animals, cats and dogs) will be transported to other laboratories of the CAHFS for diagnostic procedures that cannot be conducted at Turlock.
The Turlock Laboratory accepts all AVIAN submissions including carcasses, serology samples and bacterial cultures. The Turlock Laboratory now performs the Bovine Viral Diarrhea (BVD) Elisa test on ear notch samples.

Maybe your vet sent them to a different lab, but if he didn't, don't feel bad, my vet charged me $125 for a necropsy from UCD that I could have had done for free.
