Feather plucking in birds can be caused by physical or psychological issues. It is a complex syndrome with many potential causes including parasites, infections, injuries, behavioral issues, medical conditions, and environmental factors. A veterinary diagnosis is needed to determine the underlying cause and develop an appropriate treatment plan, which may include antibiotics, antiparasitic medications, addressing stressors, or hormonal therapy. Feather plucking can have many presentations and is difficult to deal with, but the condition can often be controlled or alleviated with proper medical care and environmental enhancements.
