A healthy young parakeet will learn everything within its capabilities if it is taught lovingly and patiently. Parakeets have a sense of tradition. They develop certain routines. When they get tired, they will retire to a chosen spot, tuck their bills into their back feathers, and probably pull up one leg close to their body. Maybe you'll hear a last, contented peep, and soon they will be asleep.
Parakeets lead nomadic lives in their natural environment.
They are adept and powerful flyers. Therefore, they should have an opportunity to fly extensively every day, preferably at the same hour each day. The gravel you sprinkle on the bottom of the cage not only serves a hygienic purpose, but is also important for the health of the birds. Special bird gravel and oyster shell mixes also supply calcium and other minerals. Flying away is by far the greatest danger.
