Bird owners urged to take precautions for avian flu
The highly contagious avian flu is being spread primarily by migratory birds, putting game birds, and backyard and commercial poultry at risk.
“Poultry owners should take precautions to prevent their birds from contacting waterfowl or the habitat that waterfowl frequent because this strain of avian influenza is highly contagious,” said Maurice Pitesky, UC Davis School of Veterinary Medicine associate professor of Cooperative Extension.
Infected waterfowl shed the highly pathogenic avian influenza virus in their feces and respiratory secretions, where the virus can remain viable for months in the environment.
“If you can't confine your birds in a coop, focus on good sanitation and reducing contact with waterfowl and their habitat such as agricultural fields and ponds,” he said.
Pitesky urges commercial and backyard chicken owners to monitor their birds for the following symptoms:
- Reduced egg production
- Trouble breathing
- Clear, runny discharge from nose, mouth and eyes
- Lethargy or lack of energy
- Loss of appetite
- Drinking less
- Swollen eyes, head, wattles or combs
- Discolored or bruised comb, wattles or legs
- Sudden death
To prevent exposure to potentially infected waterfowl, Pitesky suggests reassessing and redoubling biosecurity efforts to prevent contact between wild animals and domestic poultry.
Specifically, he recommends keeping birds away from ponds and other open water where they may contact waterfowl, which are the primary reservoir of the disease. To prevent cross-contamination, use clothing and boots that stay on your property and avoid sharing equipment with other bird owners.
A local veterinarian or UC Cooperative Extension farm advisor may have more suggestions to reduce risk.

Unusual or suspicious sick or dead domestic birds should be reported to the California Department of Food and Agriculture Sick Bird Hotline at (866) 922-2473.
Suspicious wild bird deaths can be reported to California Department of Fish and Wildlife (CDFW) at https://wildlife.ca.gov/Conservation/Laboratories/Wildlife-Health/Monitoring/Mortality-Report.
Poultry owners urged to protect birds from avian influenza virus
A strain of highly pathogenic avian influenza is currently infecting and killing wild birds and domestic birds in at least 29 states across the United States.
A UC Agriculture and Natural Resources poultry expert urges commercial and backyard chicken owners to take precautions.
“When it comes to protecting your flock, there is no treatment for HPAI so the best thing you can do is focus on biosecurity,” said Maurice Pitesky, UC Cooperative Extension poultry specialist in the School of Veterinary Medicine at UC Davis.
“In order to protect our commercial and backyard chickens, it is essential for all of us who own poultry to do our part,” he said.
The current avian influenza outbreak is already considered the worst bird flu outbreak since the 2015 HPAI outbreak when nearly 50 million poultry were euthanized or died.
The HPAI virus is being spread by migrating birds and California is part of the Pacific migratory flyway.
“Waterfowl migrate thousands of miles between wintering and breeding locations and have long been known to be the natural reservoirs for avian influenza viruses, which are associated with high mortality in poultry,” Pitesky explained. “Many of these migrating ducks, geese and swans winter in the relatively warmer climate of California's Central Valley among other locations where they can find appropriate habitat.”
Pitesky recommends preventing chickens and other poultry from exposure to waterfowl and other potential wild bird carriers.
“At the most generic level, that means making sure your birds are separated from any wildlife,” he said. “Whether you have a million-bird farm or just a few backyard chickens, the message is the same: maintain the best biosecurity you can, which includes fencing and make sure you reduce reasons for waterfowl to come near your birds such as spilled feed and ponding of water.
“Our previous research has shown that waterfowl are attracted to both natural and human-made wetlands and lagoons. So, if you live near one of these types of habitats, your biosecurity efforts are even more important.”
The HPAI virus does not currently affect humans. Pitesky said it is important to recognize that avian influenza viruses, like all viruses, can mutate or recombine to form new versions of virus that may affect humans.

Poultry 101 guides new parents of chicks
As Californians began sheltering in place at home, they started growing their own food. In addition to gardening, people have begun adopting chickens for fresh eggs. For people who have little to no experience raising poultry, University of California Cooperative Extension has care and feeding tips to keep the birds healthy.
UCCE dairy advisor Randi Black and Karen Giovannini, UCCE agriculture ombudsman for Sonoma County, collaborated with UCCE poultry specialist Maurice Pitesky in the School of Veterinary Medicine to create Poultry 101. Their tips for new poultry owners are free at http://ucanr.edu/poultry101.
“Raising chicks and hens can be incredibly rewarding, particularly with delicious farm fresh eggs made right in your backyard,” said Black, who is also proud backyard poultry parent. “However, like other animals, they take a lot of care and management to ensure they stay healthy and productive. With new poultry parents on the rise, providing informative and accessible resources is critical to keeping our backyard flocks thriving.”
The guide covers the needs of chickens over their lifespan, from the time they hatch through retirement.
For warmth, baby chicks huddle under their mother hen. Without a hen, new owners must provide the appropriate ambient temperature based on the age of the chick. Poultry 101's “Chick temperature chart” recommends temperatures for chicks from hatch to 6 weeks old.
At around 18 weeks of age, one can eggs-pect pullets to lay their first egg.
"Backyard poultry can be educational and fun. Using UCCE tools like 'Poultry 101' are meant to provide science-based practical resources to raise healthy poultry,” Pitesky said.
Got backyard chickens? Get their eggs tested for free
Californians who raise poultry outdoors are invited to get their eggs tested for contaminants.
To find out if harmful substances on the ground that are eaten by birds get passed along in the eggs they lay, Maurice Pitesky, UC Cooperative Extension poultry specialist at the UC Davis School of Veterinary Medicine, is providing free egg testing.
“We're trying to understand the connection between the environment that backyard poultry are raised in and the eggs they are producing,” Pitesky said.
Eggs from counties recently affected by wildfires will be tested for chemicals, building materials and heavy metals that may have been carried in the smoke and ash. Pitesky and Puschner are also looking for lead and PCBs in eggs from certain regions of the state.
The UC Cooperative Extension poultry specialist will share individual egg results with each poultry owner. At the end of the study, all of the results will be summarized and made available to the general public.
Pitesky describes the project in a video produced by CropMobster for UC Davis School of Veterinary Medicine and UC Agriculture and Natural Resources. Watch the video at https://youtu.be/3ZlytlUIS3I.
For more information about the study and how to package and ship eggs, visit http://ucanr.edu/eggtest.
Residents in Sonoma County may drop off eggs at the UC Cooperative Extension office at 133 Aviation Blvd Suite 109 in Santa Rosa. The UCCE office in Sonoma County is open Monday through Friday from 8 a.m. to noon and 1 p.m. to 4 p.m.
Military veterans and beginning farmers invited to poultry workshops
Workshops will be held in Davis, San Diego and Santa Rosa.
“California has the largest number of farmer veterans in the country, with over 1,000,” said Michael O'Gorman, executive director of Farmer Veteran Coalition, which supports military veterans with the resources they need to launch successful farm businesses. “Pastured poultry operations are a growing and profitable sector of California agriculture, and FVC is excited to partner with the University of California to provide trainings on this burgeoning field!”
A four-day workshop covering several aspects of pasture-poultry production will be held Dec. 4-7, 2017, from 9:30 a.m. to 4 p.m., at UC Davis.
“In addition to the more traditional topics such as flock husbandry, biosecurity, food safety, nutrition or equipment needed, we will discuss records management, marketing options and using mobile apps to capture better data,” said Maurice Pitesky, UC Cooperative Extension poultry specialist in the UC Davis School of Veterinary Medicine, who is organizing the workshops.
The poultry workshops will take a participatory learning approach, rotating between presentations, scenario discussions, Q & A sessions and hands-on demonstrations.
During the demonstrations, beginning farmers will have a chance to perform health and welfare assessments of laying hens, on-site Salmonella enteritidis testing, egg candling and safe handling.
Speakers and facilitators will be experts from UC Davis School of Veterinary Medicine, the National Center for Appropriate Technology, California Department of Food and Agriculture and UC Cooperative Extension.
Each day will include 90 minutes of networking opportunities with other beginning farmers. The registration fee is $80 and includes lunch. To register, visit http://ucanr.edu/newpoultryfarmer.
Beginning farmers will gain insightful information on successfully raising poultry flocks on pasture, as well as practical expertise, connections with other farmers and professionals in the field, and better awareness and knowledge of resources and opportunities available.
One-day workshops are being planned for Jan. 17, 2018, in San Diego, May 16 in Santa Rosa and Aug. 8 in Davis. More information will be available at http://ucanr.edu/newpoultryfarmer.
To better communicate with backyard poultry enthusiasts and to protect flocks from disease outbreaks, people who raise backyard poultry are encouraged to participate in a voluntary survey for the UCCE California Poultry Census at http://ucanr.edu/sites/poultry/California_Poultry_Census. If there is an outbreak of the highly pathogenic avian influenza, for example, UCCE will notify participants by email and warn them to keep their birds indoors.
