Hi, so I recently got a Quaker. From the start I (thought) he was amazing friendly, because he had flew out of his cage well trying to put him in and instantly stepped up with no issue. And crawled up my arm to shoulder before I could put him back in. And went right off and into his cage. He was quite and a good bird. The next day he was eager to be let out so I did and let him go to his play thing on top (his previous owner did not have a cage or toys and now dosent understand toys and hates being in his cage). Later on he went back in and was fine a few days past, still friendly but now only towards me because he had attacked two of my family members one 3 times and the other once. I was always careful and friendly as him to me. But suddenly today when I let him out of his cadge he had flew to me ( luckily I had a blanket thing to cover myself with ) and started biting me all over untill he was done. Since he seemed to have calmed down I let him out again leaving him completely alone. after awhile he had to go back in cause I had to leave and he the second I went into his room he flew to me to attack me. Again I managed to somehow get him back in. I don’t know why out of nowehere with me doing nothing wrong he’s being mean.
