The Lubavitcher Rebbe at Kaparot

Early in the morning, the day before Yom Kippur, a somber rite is performed, reminding one of the fragility of life. Penitents recite a prayer of repentance and hand a live hen or rooster to a Shochet, for kosher slaughter. The chickens will be donated as food for the hungry, and the act of charity stands the individual in good stead. Out of sensitivity to the sanctity of all life, Torah directs the Jew to cover the blood of a fowl or animal which has been spilled. A special blessing is recited upon fulfilling this command.
