If you are still molting, it is normal for myna to disobey or peck people. At this time, the master should be as kind to him as before. My myna was raised by me since childhood and is still molting. After entering the reversal period, there is no phenomenon of denying the Lord, pecking at others and disobeying. Although she is more naughty than before, she came as soon as I called her. She is a complete follower. Therefore, to a certain extent, Hachi's feelings with his master before and his attitude towards him may determine whether Hachi will disobey or deny the Lord after he enters the rebellious period. Don't speak ill of it just because it bit you or didn't listen, or myna will hold a grudge in the future. Moreover, Hachi's degree of holding grudges is not covered. Of course, under normal circumstances, he won't hold a grudge against his master, unless you don't deserve him. For example, sometimes Hachi is too soft-hearted, and I will be mean to him (this can't be done without education, and I will develop bad habits in the future). Sometimes I slap him gently, and he never holds grudges. When he scolds, he looks at me fixedly and comes to please me immediately after scolding. But he doesn't like my dad (I don't know why ... I didn't see what my dad did to him), so he sometimes attacks my dad. At first, my dad just scared him with something, but Hachi was courageous and not afraid of being scared. He continued to attack, and as he grew up, the attack became stronger and stronger. Later, my dad became very angry and began to really hit him or scare him with something. This time, Hachi will avoid me when he sees my father. But this is definitely not the end of this matter, but just the beginning, because since then, Hachi's aggression against my father has increased N times: when my father faced him, Hachi avoided me, and when he turned his back on him, he waited for the opportunity to begin. Several sneak attacks were successful, even bleeding. Once I attacked my dad's eyes when he wasn't looking. Fortunately, nothing happened, just my eyes were red for a few days. Therefore, it is forbidden to intentionally intimidate and beat and scold Bayan. Unless you are sure that he has deep feelings for you and thinks that your lessons are his own fault, you should serve him honestly to avoid future retaliation.
When it comes to anti-life, the words of disobedience, high vigilance and disowning the Lord immediately come to mind. Passing is a good thing, because the wild hachi will leave the nest and become independent after its wings are full, so its independent character begins to appear. After the first molting, it won't come out again. At this time, the host should pay more attention to the interaction with Hachi, and get him something delicious (to change his feathers better, and to cultivate feelings for the coming winter). When Hachi has decided that you are his parents, you can't just throw it away. He will stick to you like a dog skin plaster, and at the same time, he will exclude anything that he thinks will crowd out even a little bit of his position in your heart (even anything living and inanimate)
Myna is very clingy, which is why many people choose it as a pet. Other important reasons are teaching languages and letting go. Whatever it is, it is the first condition to cultivate good feelings.
I forgot to mention, I'm not so obedient. Maybe the bird has grown up and has its own thoughts, so it won't be like a child anymore. Either LZ caught Hachi or did something that made him unhappy, which may lead to Hachi's disobedience, not just a reversal period. Generally, you should molt before the end of August. Anyway, LZ recalled that Hachi began to shed feathers before she was disobedient, or did she start to shed feathers before she was disobedient? If it is the latter, it is likely to be anti-life. If it is the former, you should reflect on whether you have done anything to him, so that you can find a remedy in the future.
