Over 1.3 million chickens are being culled at an Ohio egg farm to prevent the spread of bird flu, which has had a significant impact on the poultry industry. The outbreak has been less severe this year but still resulted in the culling of 8.1 million birds to control the disease, with Iowa being the hardest hit state. Multiple states, including Minnesota, Maryland, South Dakota, Wisconsin, Georgia, and California, have reported cases of bird flu this week.
