Scientists have developed an artificial intelligence program that automatically identifies distress calls from chickens, an advance that could help farmers save thousands of fledgling lives—and millions of dollars in farm labor.
Chickens make more sounds than most of us realize. They cluck when content, squawk when frightened, and sing “buk, buk, ba-gawk” when laying an egg. Their chicks vocalize too, and they can vary that simple sound to signal pleasure or distress. Now, scientists have developed an artificial intelligence program that automatically identifies these SOS calls, an advance that could help farmers save thousands of fledgling lives—and millions of dollars in farm labor.
“The results are an important next step toward a flock welfare indicator,” says Bas Rodenburg, an animal welfare scientist at Utrecht University not involved with the study. The work could even change public attitudes toward factory farms, he says. In general, the —and farm animals in general—from empathetic producers who care about their animals’ welfare, other researchers have shown.—to attract the attention of their mother hen, whom they rely on for warmth and food. She responds with food calls, showing the chicks where to forage. But in a commercial chicken barn, chicks call out when they’re uncomfortable, socially isolated, or hungry. Answering these calls can be the difference between life and death:.
To improve these efforts, researchers at the City University of Hong Kong recorded the vocalizations of chickens housed at Lingfeng Poultry Ltd., a major poultry producer in China’s Guangxi province. The birds are kept in stacked cages , with about 2000 to 2500 chickens in each barn.
