I used the reynold's oven bags for about 8 peices of chicken, but bag said DO NOT use on anything under 8 lbs?

Question

What could happen? The bag is made for large turkey's or other birds. I put it in the oven already.

Answer 1

The bag is designed to trap the moisture from 8-20 pounds of bird and to have that set up a self basting atmosphere. With just the 8 pieces, there will be a lower moisture concentration in the trapped air to provide that basting. My strong guess is that in a short while, you will have eight delicious pieces of chicken, but possibly a little on the dry side.
