    Greetings peapeople,
    Watergoddess needs some help figuring out what may have caused the death of her beautiful peaboy (and possibly peagirl). Please see the last few pages of this thread:
    https://www.backyardchickens.com/t/801247/peacocks-dropping-tail-feathers

    I don't want her to lose any more peas - but I'm no good with pea health problems so can't give her any advice!

    If I had to guess, and it's just a guess, I would say that they died from one or more of the following:

    • Worms
    • Blackhead
    • Coccidiosis
    • e. Coli
    Probably a good idea to give the survivors a thorough examination and start them on a de-worming program that targets cecal a capillaria worms.

    Cecal Worms
    This parasite (Heterakis gallinae) is found in the ceca of chickens, turkeys and other birds.
    This parasite apparently does not seriously affect the health of the bird. At least no marked symptoms or pathology can be blamed on its presence. Its main importance is that it has been incriminated as a vector of Histomonas meleagridis, the agent that causes blackhead. This protozoan parasite apparently is carried in the cecal worm egg and is transmitted from bird to bird through this egg.
    The life history of this parasite is similar to that of the common roundworm. The eggs are produced in the ceca and pass in the feces. They reach the infective form in about two weeks. In cool weather, this may take longer. The eggs are very resistant to environmental conditions and will remain viable for long periods.
    The cecal worm can be effectively treated with fenbendazole. Since the worm itself produces no observable damage and the eggs live for long periods, it is advisable and necessary to keep chickens and turkeys separated to prevent spread of blackhead.


    Capillaria (Capillary or Thread Worms)
    There are several species of Capillaria that occur in poultry. Capillaria annulata and Capillaria contorta occur in the crop and esophagus. These may cause thickening and inflammation of the mucosa, and occasionally severe losses are sustained in turkeys and game birds.
    In the lower intestinal tract there may be several different species but usually Capillaria obsignata is the most prevalent. The life cycle of this parasite is direct. The adult worms may be embedded in the lining of the intestine. The eggs are laid and passed in the droppings. Following embryonation that takes six to eight days, the eggs are infective to any other poultry that may eat them. The most severe damage occurs within two weeks of infection. The parasites frequently produce severe inflammation and sometimes cause hemorrhage. Erosion of the intestinal lining may be extensive and result in death. These parasites may become a severe problem in deep litter houses. Reduced growth, egg production and fertility may result from heavy infections.
    If present in large numbers, these parasites are usually easy to find at necropsy. Eggs may be difficult to find in droppings, due to the small size and time of infection.
    Since treatment for capillaria is often lacking, control is best achieved by preventive measures. Some drugs, fed at low levels, may be of value in reducing the level of infection on problem farms. Game birds should be raised on wire to remove the threat of infection. As some species of capillaria have an indirect life cycle, control measures may have to be directed toward the intermediate host. Hygromycin and meldane may be used for control. Additional vitamin A may be of value. Effective treatments that are not approved by the Food and Drug Administration are fenbendazole and leviamisole.

    Causes of Mortality in Backyard Chickens in Northern California: 2007–2011

    SUMMARY​
    A 5-yr retrospective study was conducted to characterize the spectrum of diseases causing mortality in 1301 backyard chickens submitted to the California Animal Health and Food Safety laboratory in Davis, California. Infectious diseases were diagnosed in the majority (60.4%). Viral diseases comprised 50% of the infectious entities, followed by bacterial diseases with an incidence of 39%. Marek's disease in the viral group and Escherichia coli in the bacterial group were the most commonly diagnosed infectious diseases. Zoonotic agents including Aspergillus sp., Salmonella sp., Listeria sp., Mycobacterium sp., Candida sp., and Baylisascaris sp. were detected in 46 (3.5%) birds. Among noninfectious conditions, fatty liver hemorrhagic syndrome and reproductive tract adenocarcinoma were the leading causes of mortality. This analysis provides an overview of backyard chicken diseases for practitioners and avian pathologists working with backyard poultry. In addition, this study illustrates that backyard chickens do not seem to pose a major risk to public health, although zoonoses do comprise a notable portion (5.9% of all infectious cases) of isolated agents.
