Chicken amounts for 50

Hi all, I'm doing a catering jog for 50 guests, we serve buffet style and I have never done just chicken. We usually always do pulled pork and something else if they want a 2nd meat but this is a 1st for chicken only. I am doing legs, thighs and wings. It is a class reunion so I figure people won't eat as much, we will be serving for 1 hour. I am figuring 60 each of thighs wings and drumsticks. What do ya think is that enough?

I went with thighs, legs and wings and had 50 thighs, 72 drum sticks, and 72 wings. This was a 20 year high school class reunion and what happened was people were more in to I guess nerves of seeing old class mates and drinking. So these firgures probably would not work for a family reunion but each person coming through line ate one piece of chicken and some were too busy drinking to even eat. hardly anyone touched the wings, I guess being dressed up they did not want to get deep in to pickin a wing apart. There ended up only being about 40-45 guests and I had half the chicken left over. This was my first class reunion catering gig and if they are all like this then class reunions groups don't eat much. Just thought I would post the results, thanks again.
