It is better to prepare a larger cage for the red-billed blue magpie. The small bamboo cage is too small for it. A metal cage with a larger space would be a very good choice. After all, they are not relatively petite in size.
Change the water once a day, and usually give some meat and other food to strengthen the body. Before the tail is cut off Tie the tail together before breaking it so that it won't break. If it's half broken, pull out the half. A new one will grow out in half a month.
