Illustration of chickens which will be used as part of the Kaparot ritual in which the chicken is swung over one's head in belief that one transfers the sins from the past year into the chicken. The ritual is performed before the Day of Atonement, Yom Kippur, the holiest day in the Jewish year. The chicken is later slaughtered and given to charity. September 26, 2017.
