Chicken accounts for a third of the global meat consumption, demand over chicken meat has seen a dramatic rise in the past decades. A 2014 study compared the growth rates of the modern broilers with chicken strains from the 70s and 50s. The study found out that the modern broiler chickens have an exceptionally faster growth rate and a much bigger body mass compared to chickens from the past generations.
The rapid weight gain is a result of intensive farming and heavy commercial selection. The common broilers are specifically bred for rapid growth, which has allowed broilers to reach slaughter-weight quickly while taking up less feed. This reduces the cost of chicken meat production and made chicken an affordable meat choice.
Although this meant more chicken meat can be produced with less resource and time, chickens reared under intensive conditions are subject to poor living and health conditions, raising welfare concerns.
