| CHICKEN | 2022-03-01 | 1 | +21.4% | 2.3 | The H5N1 outbreak confirmed in US flocks in early February 2022 raised fears of poultry supply losses and export bans, supporting chicken prices; early culls were mostly layers and turkeys, so broiler supply impact was limited and other factors (feed costs, strong demand) likely also contributed. |
