What tell-tale signs signal a flock is likely dealing with coryza upon initial observation?

Answer

Snicking, rattling breathing, or watery discharge from the eyes and nostrils.

The initial clinical indication that a flock is suffering from Infectious Coryza typically involves specific upper respiratory distress signals. These familiar sounds and visible signs are what poultry keepers use to identify the onset of the ailment. Specifically, the characteristic sound of snicking or rattling breathing, often accompanied by a visible, watery discharge emanating from the bird's eyes and nostrils, points strongly toward an active upper respiratory infection like coryza. These signs reflect the inflammation and exudate buildup occurring in the upper airways due to the bacterial invasion.
