<h1>Fact-Check: Backyard Chickens Aren’t Safe From Bird Flu</h1>
 As egg prices continue to skyrocket across the United States, some consumers are looking for alternative ways to secure affordable eggs, including turning to their backyard. Last month, U.S. Secretary of Agriculture, Brooke Rollins, penned a commentary outlining her <a href="https://sentientmedia.org/avian-flu-plan-hatched-usda/">plan to help “lower egg prices.”</a> Among her proposals — such as vaccinating chickens and reassessing California’s Proposition 12, which tightened animal welfare laws — there was also a nod to <a href="https://sentientmedia.org/backyard-chickens-avian-flu/">raising backyard chickens</a>.
In her commentary, Rollins writes that part of the plan is “to make it easier for families to raise backyard chickens.” There was no expansion on this point, however, outside of a sentence in the USDA release of the plan promising to “minimize burdens on individual farmers and consumers who harvest homegrown eggs.” A spate of <a href="https://civileats.com/2025/02/18/op-ed-egg-prices-are-soaring-bring-out-the-backyard-hens/">articles</a> also suggests the notion is <a href="https://www.theguardian.com/us-news/2025/feb/23/florida-backyard-chickens-eggs">picking up steam</a>. Yet even though the idea may seem like a potential solution to rising egg prices, research suggests that keeping chickens for eggs may just bring the risks of avian flu to your backyard. In short, because your backyard is not protected from wild birds. 
“The more birds that you have, especially when they kind of overlap with waterfowl habitat, for example, the increased risk you’re going to have [of bird flu],” Maurice Pitesky, associate professor and expert in poultry disease modeling at the UC Davis School of Veterinary Medicine, tells Sentient.
The increased risk applies to industrial egg operations. Nearly <a href="https://ourworldindata.org/how-many-animals-are-factory-farmed">99 percent of farm animals in the U.S.</a> are raised on factory farms — operations where animals are crowded together, often in unsanitary conditions. These <a href="https://sentientmedia.org/zoonotic-diseases/">settings are breeding grounds for diseases</a> like bird flu, as the density and poor care make it easy for viruses to spread quickly. But it's not just factory farms that are at risk. In the past year, bird flu outbreaks have made headlines across the United States, and backyard chickens have not been immune to its reach.
<h2>Backyard Flocks Impacted</h2>
Over the last 30 days, <a href="https://www.aphis.usda.gov/livestock-poultry-disease/avian/avian-influenza/hpai-detections/commercial-backyard-flocks">51 backyard flocks across the U.S.</a> have confirmed cases of avian influenza, compared to 59 cases in commercial operations, as of March 3. While the number of affected backyard flocks is slightly lower overall, it’s important to remember that the risk to smaller, home-raised flocks remains significant, primarily because the disease is often spread through wild birds — including their droppings and saliva — who can easily get to a backyard flock.
Wyoming recently reported its first human case of bird flu, which is believed to have been contracted from exposure to a backyard flock. The first <a href="https://www.cdc.gov/media/releases/2024/m1218-h5n1-flu.html">severe case of avian flu</a> in the U.S. occurred in December 2024 in Louisiana, where it was determined that the person had been exposed to sick and dead birds from a backyard flock. This person also became <a href="https://ldh.la.gov/news/H5N1-death">the first person in the U.S to die from the virus</a>.
“This case underscores that, in addition to affected commercial poultry and dairy operations, wild birds and backyard flocks also can be a source of exposure,” the <a href="https://www.cdc.gov/media/releases/2024/m1218-h5n1-flu.html">Center for Disease Control has stated about this case.</a>
Bird flu can spread to people through various routes in a backyard farm, according to the CDC, including direct contact with infected birds, their droppings and contaminated equipment.
<h2>The Spread: Wild Birds and Backyard Flocks</h2>
It’s tempting to assume that backyard chickens are safer from bird flu than large commercial farms due to their smaller flock size and less crowded living conditions. But this assumption overlooks the critical role of wild birds in spreading the virus.
The virus is frequently carried by wild birds, many of which are migrating across the country. For backyard chicken keepers, this poses a serious risk, as wild birds can <a href="https://news.uga.edu/wild-birds-and-backyard-chickens/">easily come into contact </a>with their flocks, potentially bringing the virus with them.
Benjamin Anderson, an assistant professor in the Department of Environmental and Global Health at the University of Florida, told Sentient in an email that wild birds, particularly ducks and geese, are the main carriers that can introduce the flu into backyard flocks. Outbreaks are also more concentrated along migratory bird flyways, Anderson noted, with four major routes across the U.S.
A 2021 study on <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC8161317/">avian flu transmission pathways</a> found that flocks near or in contact with waterfowl and migratory birds are at a higher risk of infection. Although the study primarily focuses on commercial farms, its insights are also relevant to backyard operations —&nbsp;in essence, the researchers found that the virus can spread more widely when chickens aren’t properly isolated from these outside threats. Infected birds can release the virus through their saliva and feces —&nbsp;in other words, exposure doesn’t require direct contact with a backyard chicken.
Though backyard chickens are often not as crowded together as chickens raised commercially,&nbsp; birds raised in backyards are vulnerable to bird flu thanks to the lack of strict biosecurity regulations. Unlike commercial farms, which are at least required to follow certain guidelines to prevent outbreaks (such as regular testing and isolating infected animals), there is no oversight or enforcement for smaller, home-raised flocks.
With backyard bird flocks, says Pitesky, “their biosecurity on average is not ideal.” There are a number of reasons why that can be the case, including a lack of “adequate fencing.” It can even be as simple as the hobbyist may be pressed for time. “People have lives,” says Pitesky. To keep backyard chickens safe, Pitesky says, “it takes some time and energy and money.”
Backyard chicken keepers may not be aware of the measures they should take to minimize risk of exposure. A 2024 survey study in the UK of 1,550 poultry keepers found that not all <a href="https://www.sciencedirect.com/science/article/pii/S0167587724000035#sec0085">backyard poultry owners were following biosecurity measures</a> mandated by the government. The researchers found that some poultry keepers were unaware of what was required of them or faced barriers such as expenses, fewer carers for the birds and other welfare concerns.
The CDC has <a href="https://www.cdc.gov/bird-flu/caring/index.html">issued guidelines</a> for backyard chicken owners to follow, such as restricting human access to their chickens, keeping them in enclosed spaces and minimizing exposure to wild birds. But if backyard chicken keepers do not implement these protocols effectively, the birds are left exposed to the virus.
<h2>Should You Raise Backyard Chickens During a Bird Flu Outbreak?</h2>
Anecdotally at least, Anderson has found that more people are interested in having backyard chickens these days, especially with high egg prices. And though both Anderson and Pitesky see the appeal of having backyard flocks, they also point to the risk associated with keeping them.
It’s crucial to understand that keeping backyard chickens during an outbreak requires significant research, preparation and strict adherence to CDC guidelines. The <a href="https://www.cdc.gov/bird-flu/caring/index.html">CDC recommends wearing personal protective equipment (PPE)</a> when handling sick or dead birds, cleaning and disinfecting contaminated areas and avoiding stirring up dust or&nbsp; bird waste that may spread the virus. In an email to Sentient, Anderson writes “people should take necessary steps to learn how to raise poultry safely and according to local and state rules.”
However, this guidance quickly becomes complicated —&nbsp;some infected birds (especially those that are infected with a low pathogenic strain of bird flu) may not show symptoms. This strain can then mutate into the highly pathogenic version. As a result, flock owners may not realize they need PPE or take proper measures when dealing with asymptomatic birds. They may end up spreading the virus unwittingly.
<h2>The Bottom Line</h2>
Though the current risk of contracting bird flu remains low for most of the public, the middle of a bird flu outbreak may not be the best time to start keeping backyard chickens. It may sound appealing to be able to source “free” eggs from your backyard, but the reality is that keeping backyard chickens safe from bird flu requires time and money. And ultimately, raising chickens in a backyard doesn’t eliminate the risk of spreading the virus, and could even exacerbate the problem if you don’t take the proper precautions recommended by the CDC.
As for Secretary Rollins' plan to make raising backyard chickens easier for homeowners, the details remain unclear. Sentient reached out to the USDA for more information on how her plan addresses these concerns, but has yet to receive a response.
Clarification: this piece has been updated to distinguish between the USDA press release and the commentary from the Secretary.
