What is a nesting box and should I buy one for my budgies?
Unlike some other bird species, budgies do not collect materials and build a nest. In the wild, budgies nest inside hole in trees. Domestic budgies use nest boxes provided by their owners. Nesting boxes are basically a small box with a entrance hole that domestic budgies use as their nest to lay eggs in and raise families. The presence of a nest box will often produce mating and nesting behaviors in previously unpaired budgies and even in singles hens so if you do not want to urge your budgies into parenthood, do not supply a nest box. Some cages are specially equipped with trap doors or removable sections where nesting boxes can be added to the outside of the cage.
