The food of the colorful bird is simple, mainly shelled millet, with some eggs and millet, but it must be clean, especially the drinking water must not be contaminated.
The Golden Back, the Colorful Munia, is particularly susceptible to illness and death. The most common one is weather changes, which can lead to diarrhea if you catch a cold!
