The floor may be poured with high outer edges sloping toward a center drain, preferable of good size with a removable wire basket to aide in cleaning. A high center sloping to the outside on two sides may be used. Another solution is to have the entire floor slope toward one side with a trough carrying the water to a drain. Good provision for drainage requires careful planning if a very messy situation of soggy ground and unsightly collection of debris is not to result. Providing electricity for both heating and light is advisable.
Electric heating is really the only safe method.
We have found that providing a dim light at night protects the birds from injury if they are startled. Having a supply of clean, running water is another convenience. If the only source of water is a garden hose during the warm weather an excellent medium for growing bacteria is provided. The hose must be changed at frequent intervals for a new one, and the water allowed to run through before each use for sufficient time to thoroughly flush the interior. Many outbreaks of disease in aviaries have been traced back to a contaminated garden hose.
