How are you going to get the chicken, in pieces? If this is how you get them. I could only find a case with 16 head cut into 8 pieces. That would give you 128 pieces and you would need at least 19 cases if everyone was to get one piece. Maybe more if you don't count wings. Your pulled pork yield might be high. I usually use 50% yield. So you would need to cook 1000# of pork. I have no idea on the tri-tip.
