Activists cried fowl Wednesday over Mayor de Blasio’s refusal to enforce animal-cruelty laws against Orthodox Jews who ritually slaughter chickens ahead of Yom Kippur — claiming he is motivated by the fact that the community is a powerful voting bloc.

Attorney Nora Marino made that argument before the state Court of Appeals for Brooklyn residents calling themselves The Alliance to End Chickens as Kaporos. The rite is a 2,000-year-old tradition in which believers absolve their sins by sacrificing chickens. Opponents say the practice is inhumane and unsanitary.

City attorney Elina Druker said forcing the NYPD’s hand could fail: “They’d have to arrest 60,000 people, a religious minority, on the eve of their high holiday.”

But senior Judge Jenny Rivera said Marino wants “to show that it’s not about deployment of resources, it’s about favoring a particular class.”
