Yup, in Singapore you probably won't get to see this at Seng Choon egg farm since they only have hens and not roosters. According to this report,
the hens are of American origin and they are only kept for a year to lay eggs before being slaughtered for food.
This means that annually, Seng Choon egg farm will replenish their female chicks supply from America. This demand ensures the continual grinding of the American male chicks and the annual killing of the expatriate American hens.
Imagine yourself as one of the American female chicks. You heard your brother screaming as he was ground alive. Then you got clamped in the head by some mechanism and got yanked to another place while feeling a sharp burning pain in your beak. The pain will stay on for weeks, months and maybe until you die. You find yourself in another country far away from your birth place where the days seem to be always longer than nights. After a year of laying eggs, you end up as dinner on someone's plate. And you remain a wandering soul in a foreign land.
