Buy a big cage
Housing your budgie is an important aspect of his care requirements. The size is one of the most important things to look at when setting up your little guy's cage. In general, your budgie needs room to play, fly, hop, eat, drink and poop without interference. The standard minimum cage size recommended by bird professionals is 12- by 18- by 18-inches for a single bird.
The cage needs to be big enough for toys, treats and perches.
- Try to buy a cage that is wider than it is tall and with a square top. Budgies fly horizontally, not vertically like quails. Fancy-topped cages are simply a waste of space and money.
- Do not buy a circular cage, as a budgie cannot stretch its wings and fly properly in one.
- Your budgie must be able to spread its wings and fly. Do not crowd the cage with toys, perches or other budgies.
- Test a few cages and look for one that you can clean easily. Can your hand enter the cage easily? Can you use a brush inside it? Remember that budgies poop every ten to fifteen minutes!
- You can keep the same cage if you decide to have one more budgie. Try to buy a bigger model if you have more than two.
