For profitable poultry production (as well as having a 'happy' flock) it is important to maintain a healthy flock. The well-known quote "The best defense is a great offense" holds true when keeping poultry. A strong biosecurity program is important to keep disease-causing organisms (bacteria, viruses, fungi, etc.) away from your flock.

To understand the effects of disease-causing organisms (as well as management problems) on the health of your flock it is important to have a good understanding of the anatomy and physiology of poultry and what the inside of a healthy bird looks like.
