A bird needs at least enough room in a cage to spread its wings and turn around without tail damage. Bird safe paints and materials should be used (no galvanized metal or lead based paints).
Birds should be located in an area away from kitchen fumes, places that may be drafty (like under vents), or that may get too hot or cold due to placement too close to a window. If your bird is in a location that will be brightly lit late at night, you can use a sheet or cage cover to provide privacy and dark to sleep by.
Most birds do best with complete pelleted diets supplemented with seeds, fruit, vegetables, and occasional protein based treats such as cooked chicken. The best words of advice we can give is to provide a healthy, varied diet - don't just stick to a seed mix.
