My bird is aggressive...
My bird (cockatiel) has become more aggressive and i don't know why. Not a lot of things have changed. Maybe I don't spend as much time with him as I did, I got a new boyfriend recently and am not at home that much and he spends more time in his cage. He's packed with toys and the best seed out there.
He's 1 and 3 months and he has arthritis on his wing (since he was 3 months old), that was about 2 weeks after I got him and he's 100% my bird/pet (I'm 15, almost 16 now).
So, why is he being so aggressive?
