What's wrong with Huang Yan without breeding?

The reason why Huang Yan does not reproduce is because it has not yet matured, or it may not be in the reproduction period.This kind of bird can breed 2-3 nests a year. The male birds will first call to attract the opposite sex pairing, and then build a nest on the branches.Each egg can produce 4-5 eggs per nest. The incubation period is about 13-15 days. After that, the male and female parenting birds will have a common breeding.
