What's wrong with the Xuanfeng parrot without breeding?

Xuanfeng parrots do not reproduce because of environmental discomfort or because they are less than age.The breeding period of this bird is from August to December, but as long as the climate is suitable, it can breed all year round.The nest will be built in the tree hole, and at the same time, I have a strong sense of territoriality. I can produce 2-5 eggs every time. The incubation period is about 19 days. The female and male birds will participate in the breeding.When you are, you will leave the nest.
