Tamed cockatiel became aggressive

[G12sbmx]

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

Hi there, and welcome. There can be so many reasons for aggressive behaviors in parrots. Molting, hormones, and coming into adulthood are some of the big ones. Do you see any pin feathers coming in? Does your cockatiel hang out on the bottom of the cage? Have you consulted a vet? That may be a good place to start. Usually they can run labs, and make sure nothing major is going on.

Most likely, hormones! Just love him and don’t push the relationship! He will come around!

We have a very similar story. Ours is almost a year and it seemed out of nowhere he became aggressive. I have really paid attention to the surroundings of what is going on, but he will come out of his cage and be ok for a few minutes then its all aggression after.

Hey yes i see some feather coming out, sometime he removes the damaged ones like in the photo bellow! If it gets worse the next days i will take him to the avian vet! Thank you for your help
