Hey there,
Hope u all having a good day! I have 9 mounths old cockatiel, i got him from day 14 and hand-raised him. Recently I realized that he became my aggressive than before, he doesn’t even let me pet him like before and he is biting when i try to pet him. He doesn’t even singing like he used to. Any idea what the problem could be? Sorry for bad english
