the motley crew:

and in the back there, the "slaughtering field" of the chickens:

MONSEY, N.Y. (AP) ― An organizer has been fined $3,000 for leaving a mess on a suburban county's property after conducting an ancient Jewish ritual that involves slaughtering chickens.
Moshe Lefkowitz told the Rockland County Board of Health Wednesday that the fault lay with his 18-year-old son.
(Note: This is NOT his son)
Some 11,000 live chickens were on hand at the onetime Rockland Drive-In in Monsey for the kapparot ceremony in September. Some Jews conduct the rite ahead of Yom Kippur, or the Day of Atonement. Kapparot entails prayer, symbolically casting away sins by swinging a live chicken overhead, slaughtering the birds and giving them or donations to the poor.
Rockland health inspectors said the former drive-in was coated with chicken remains, insects and trash after the ceremony last year.
Have You Seen My Chicken...?

I lost my chicken the day before Yom Kippur. You may be wondering why that is a problem...
