Why does my macaw have scabs? What causes bird skin issues?

Updated On September 23rd, 2025

Pet's info: Bird | Unknown - Bird | Male | 18 years and 3 months old

My hyacinth macaw is covered with scabs. We thought it was the rough winter and a very dry house, so we upped the humidity and apply raw coconut oil to the affected areas every day which helps, but new scabs keep popping up and the problem doesn't seem to be going away. What else could cause this kind of skin problem? He eats mostly macadamias but regularly gets fruit (bananas, grapes, mango) and sweet potatoes. I have started crushing up high quality pellets with his nuts to up his nutritio

This may be due to a nutritional deficiency or infection (parasites, bacterial, fungal). Ideally, Scooby should be examined by an experienced avian veterinarian for a diagnosis. He can have about a dozen macadamia nuts daily, but you can mix it up and give a few Brazil nuts or hazelnuts as well. Almonds and pistachios are also healthy options. Try to get him to eat as much of the commercial pelleted diet as you can. It may be difficult transitioning him but it will be healthier in the long run. You can also bathe or mist him once or twice a week to encourage preening and to promote healthy skin and plumage. Clean and sanitize his cage. bowls, toys and perches. Discard anything that cannot be sanitized. Clean the cage bottom daily to prevent attracting pests.
