I just wanted to update this thread with one more post, and a thank you to JLcribber!
Ive read all his articles/threads he posted for me. I have read all with careful consideration. (English is my second language, so its hard sometimes to comprehend things. But ive tried my best even if some things are fuzzy. Usually I'm better speaking, not reading :/)
I think i may have gotten a bit into the problem with my friend
One, we've narrowed it to agression is normally shown to my boyfriend
Two, she notices Snowball may see my boyfriend as a threat, and i may be seen as his mate. (I noticed he's been trying to regurgitate on me, and i know this could be fairly innocent but given other things, my friend said it may as well be a courtship gesture.)
Three, he gets along with women more than men. My friend isnt sure if this is his hormones or just what he is used to, since his previous owners were all men. She said lack of experience with men may make him nervous.
Four, she thinks this may be a mixture of poor living prior, hormones, and dominance because of his bevhavior being unpredictable. She told me its fairly common in rescue cockatoos because we arent sure of their previous lifestyles/treatment/ how they were pet etc.
As for using his cage for time out, ive just been putting him in his cage with the door open, as one of the articles suggested, or on his perch while i do something else.
I'm very determined to figure this boy out, and I will never ever give up on him! That being said; i realized i never shared a picture of my baby, this was taken a while ago, when I let him on me, as i try not to bother him with cameras during our training. Gosh, this was like maybe our first week with him?
