Food & NutritionWhy does my cockatiel have bald spots under wings and grey feathers?
The grey covering is a sheath that is on new or developing feathers. His skin looks irritated which may be due to parasites or infection. Ideally, he should be examined by your veterinarian or an experienced avian veterinarian.
Clean and sanitize the cage, bowls, perches and toys. Discard anything that cannot be sanitized. Transition him to s commercial pelleted diet such as Harrison's, Lafeber, Exxact or Pretty Bird. You can supplement with a small amount of a fortified seed mix as well as with fresh vegetables and fruits.
