Raising mountains is always a long process. Don't think about its singing and sex. Let it get used to being caged and get along with human beings in a common living environment, and then it will naturally recover its singing and sexual ability until it fights. Specific practices:

First, let it see more people and hang them in noisy environments, such as roadsides, intersections, units or shops, open-air tea shops and other places. Only a small corner is opened when hanging, so that it can see more of the noisy world of human beings. With the passage of time and the stability of birds, it will gradually open its clothes. At this time, it will no longer be afraid of the world and dare to sing. Second, don't give it good bird food, let it have a strong appetite for live insects, so that you can often tease it with live food in your hand and let it peck. After a long time, it reached for the cage and pulled open its clothes, so it was not afraid. Third, we should often take him to places where bird friends walk birds, but for a period of time (ranging from a few months to more than a year, depending on the individual differences of birds), we should hang him far away, with his clothes only slightly open, so that he can see the beatings, pecking and attacks of his companions in the cage from a distance, so that he can gradually get used to living in the cage and show his nature like other companions. The fourth is to take a bath frequently. Changing cages more often, bathing frequently and changing cages frequently can really promote thrush to accept human domestication and new living environment. Fifth, before the old man is locked in a cage, he must not tease the mother bird and try to avoid the cry of the mother bird. Experience has proved that the old man didn't tease the mother bird or imitate the singing of the mother bird before releasing it, but it would prolong its cage release period.

Generally speaking, after more than one year of domestication, the old people in your mountain can generally walk up and hang up like other birds and compete with each other.
