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.
