While it is true they are not sensitive it's still bad to force feed a chicken powdered anything unless mixed with water.No, force feeding maybe bad, but the fact it was pepper is irrelevant. The reason peppers are spicy to mammals, whether in or out the other end is not because they are physically burning, but because the cells in & around the mouth, rectum and anus are sensitive to capsicum. When was the last time food was spicy in between your mouth & anus? lol Chickens don't sense capsicum at either end, thus it's not an issue.
