Worsening Bird Flu Outbreak Highlights Factory Farm Threats
Factory farms create the ideal breeding grounds for infectious diseases like bird flu. The vast majority of U.S. broiler chickens (78%) and U.S. egg laying hens (75%) are raised on factory farms, averaging over 175,000 and 850,000 animals per operation, respectively. Dairy cows, beef cattle and swine are raised in similarly cramped conditions.
