On a monitor in The Departed (2006), Sullivan identifies everyone present with Irish Mob boss Frank near the building that they have under AV surveillance nearby. Frank checks his phone and sees a message from Sullivan that reads "No phones."
Sullivan: Time is 10:46.
Frank and his gang enters the building:
Frank: All right, turn off your cell phones. Fitzy's got the chicken. Check your weapons.
What does "the chicken" refer to?
