Highly pathogenic avian influenza was confirmed on October 28 in a commercial flock of 1.3 million laying hens in Stanislaus County, California, the state's first commercial poultry detection this fall. It follows an outbreak of 934,600 hens in Clinton County, Illinois, under three weeks earlier.
Lost layers reduce egg supply, and California's Proposition 12 cage-free rules prevent quick imports from conventional farms, so the state's wholesale egg premium could widen. Feed demand from layer flocks falls only slightly in this case.
