I have a 2 year-old GCC. His name is Bucky and I love him to death but as of the last 8 months he has been very mean. When he would typically let me pick him up and cuddle him he puffed his feathers up and bites me. Just now he flew over to me and was relaxing on my shoulder and then bit me and wouldn't let go without me having to throw some fabric at him to even get him off. At night when all the lights are off he will fly over to me desk and become the biggest cuddle bug but any other time all he wants to do is bite me. I don't know what I did or am doing wrong for his behavior to be so weird towards me. I got him when he was 6 months old. The breeder said he was hand raised so I don't know why he became so chompy. I'm just puzzled as to what to do at this point to get him to go back to his loving self towards me. Hes like this with everyone tho..one wrong move and he will bite, or if you have him and try to put him back ontop of his cage he still bites.
