Hi everyone! My male yellow sided green cheek has been so aggressive lately. He at random decides my hand is evil and will seek it out to attack! I've tried to read the signs as to what might upset him and why he might want to attack my hand at a certain time but it just seems to be random!! He was so sweet, he did bite but there was always a reason and he never used to seek me out he's been doing this from the day I changed around my room. I moved my bed and moved out this old branch and put a new one in the room. Do you think this upset him? He is showing all the signs of being hormonal but he's only 9 months old? He gets 12 hours of uninterrupted sleep, I don't provide any dark hiding places or mushy food. I've tried ignoring him, shaking him off, making a funny noise those work but then he just does it again. The bird trainer also said to put a bit of pressure on his beak when he bites but that just makes him more mad. He bites so hard it bleeds, my hand is really ripped up please help!!!
