It’s actually a layer of keratin sheath residue which protects growing feathers and eventually breaks off when they self preen or when flocks preen each other. If your bird has another bird companion, you don’t need to worry about doing this, but if they’re the only bird you have, then you need to do this for them on the spots they can’t reach themselves! • • • • #bird #birds #pet #petsoftiktok #quakerparrot
