Galvanized cage bars and metal water containers that are soldered at the seams can cause lead poisoning in your bird. For the bottom of the cage, materials such as newspaper, paper towels, paper bags and butcher paper should be used. Paper does not promote the growth of pathogens, and should be replaced daily. The entire enclosure should be thoroughly cleaned weekly. Cleanliness limits the bird's exposure to droppings, and increases its chances of staying healthy.
Perches are also an important part of the cage.
A perch should be made of nontoxic hardwood branches that are free of chemicals or pesticides. Perches should vary in diameter. Providing different thicknesses of branches can prevent foot problems, so the bird's foot will not be in the same position all the time. It is best that the perches be irregular in cross section, and not perfectly cylindrical. Otherwise too much pressure may be placed on the same area of the foot, resulting in foot problems.
