Yields vary dramatically: some farms produce as much as 150 pounds per acre each year while others produce little. Typical yields in Europe range between 25 and 35 pounds per acre each year, but as methods improve many more farms are achieving yields in excess of 100 pounds per acre.
With bodies taxed beyond belief, chickens who survive their time in production are often slaughtered at just 42 days old. They are still âpeepingâ the sound of baby chicks when they are killed â even though their bodies have ballooned to the size of giant adult chickens in this short time due to industry practices.
Now to the figures. Itâs estimated that 108 million people were killed in wars throughout the 20th century with estimates for all of human history coming around 150 million to 1 billion. Some hard and fast numbers we do have for animal slaughter are from the USDA for 2013. In that year alone the united stated slaughtered 8.6 billion chickens. so we have: 7.6 billion more chickens were killed in a single year in a single country than all the humans who have ever died from war. And that is even going with the highest estimation of human deaths. G lobal chicken slaughter is estimated at 50 billion.
