If the family becomes very busy, or you would like to try breeding cockatiels, you can add a second one to your collection at a later date. Keep a new cockatiel in a separate room from an existing bird for at least 30 days. New birds need a safe, clean cage in a quiet location. Water can also be offered in more than one location until the bird is oriented. Use perches of several different diameters to exercise the feet properly.
Most veterinarians recommend fresh, natural branches as part of the cage furniture.
Your cockatiel will enjoy perching on these and peeling the bark from species such as apple, alder, beech, maple, eucalyptus, citrus and many others. Toys are highly recommended for such intelligent birds as cockatiels. Those with mirrors, open bells and chewable items such as rawhide and plaster are particularly valuable for cockatiels. Check with your retailer and veterinarian about toy safety for your particular bird. Always select the largest cage you can afford.
