It is normal for a cockatiel to sneeze a few times a day to clear out dust or dander from its nares, which might be accompanied by a clear discharge. If the sneezing is persistent and/or the discharge is not a clear color, contact your avian veterinarian. Cockatiels are excellent fliers and need more frequent wing clipping than other parrot species because they are capable of flying not long after having their feathers trimmed. Cockatiels molt (shed old feathers and begin growing new ones) a couple times a year.
A main health concern for female cockatiels is chronic egg-laying, which can deplete her body of vital minerals and calcium, as well as egg binding, in which the hen is unable to pass an egg. (A hen does not need a male cockatiel present in order to produce an egg; it will just be an infertile egg.) Female cockatiels, therefore, often need extra-calcium in their diet, such as a calcium-fortified base diet or a supplement like cuttlebone. Since cockatiels are often fed a mostly seed diet, many suffer from malnutrition and vitamin and mineral deficiencies. An all-seed diet is also high in fat, which can lead to fatty liver disease. A healthy, low-fat diet with the right balance of vitamin, minerals and amino acids can go a long way in preventing disease in your cockatiel. The Lafeber Company offers many diets, including, Premium Daily Diet Pellets and Classic Nutri-Berries that are specially formulated to meet your cockatiel’s dietary needs.
