America's chicken has gotten 4 times bigger since 1957, and researchers say it wasn't hormones
America's supermarket chicken has been remade over the past several decades into something far removed from the bird many families bought in earlier generations.
Research shows today's broilers reached more than four times the weight of a 1957 chicken by the same age, and scientists said hormones were not what caused the jump.
Here's what to know
No other meat is eaten more in the United States. ZME Science reported that chicken makes up over 40% of all meat consumed, and per-person consumption hit 104.5 pounds in 2025. Supplying that level of demand drove breeding practices that changed the birds themselves.
