What's wrong with Blue Ge Not breeding

The reason why the blue song is not reproduced is usually because the birds are not mature, or they have not yet reached the breeding period.This kind of bird is currently unable to reproduce artificially. The population in the wild will be screamed to find a spouse when the breeding period will be built. After completing the pairing, it will start to build nests. The nests are made of deed, branches, and moss.After the nest is built, the female will produce eggs, and each nest can produce 5-6 pieces.
