A common sign of aspergillosis?

• A. Heavy breathing
• B. Lameness
• C. Coughing
• D. Feather loss

Answer: (A)

Respiratory infections like aspergillosis disrupt the airways and lungs, so signs center on breathing. Heavy or labored breathing is a direct consequence of airway irritation and obstruction from the fungal infection, making it a common and telling sign in affected birds. Lameness points to leg or joint problems, feather loss to skin or molt issues, and while coughing can occur with airway disease, the more consistent and obvious sign here is the difficulty with breathing. This helps you recognize respiratory involvement early and seek prompt care.
