Sacrifice - (equal time)

On Saturday, Sept 18, 2010, The Sun ran a picture captioned "Sins remembered on Day of Atonement" noting the symbolic transfer of sins to a chicken. The chicken is later slaughtered and donated to the poor. As with the Muslims' goat (see earlier post), wouldn't a wafer be more humane? (Besides, why do the poor want a chicken with sins when your typical chicken is sinless?)
