Millions of chicks shriek helplessly as they are thrown into a truck where they are suffocated and stamped on by men.
The footage is reported to have been secretly filmed by a worker at the poultry farm in San Miguel del Monte, Argentina.
After farming company Rasic went into decline, they became unable to feed the chicks and decided to kill them – which is apparently routine practice in Argentina.
Local papers have reported the number of baby birds killed was nine million.
