Overview
Scaly leg disease, also known as knemidocoptosis, is a common parasitic condition affecting birds, particularly chickens, turkeys, and various pet birds such as parakeets and canaries. It is caused by Knemidocoptes mites, which burrow under the scales of a bird's legs and sometimes the face, causing irritation and thickening of the skin. In poultry such as chickens and turkeys the responsible species is Knemidocoptes mutans, while pet birds such as parakeets and canaries are affected by Knemidocoptes pilae.
Causes
The primary cause of scaly leg disease is infestation by Knemidocoptes mites. These mites are microscopic and thrive in poor hygienic conditions, making them more prevalent in environments where birds are kept in close quarters without regular cleaning.
