What should I do if my brother does not eat

If Brother does not eat, let it be hungry for a while, and then feed it.Or cover it with a cage cloth so that it can not see the situation outside, so it is easy to eat.This kind of birds can eat insects in the wild, and they can also eat the fruits of plants. If they are raised artificially, use bread insects, meat, rice, etc. as feed. Regularly match some vegetables to supplement nutrition.
