The company said on X that it first noticed mortality in the layers on January 25 and quickly sent samples for testing. Rose Acre Farms has operations across the country. The Seymour, Indiana, facility is located in Jackson County. The Indiana Board of Animal Health of Animal Health on January 26 announced that the virus had been detected at a layer farm in Jackson County that has 2.8 million birds.
