Hello, welcome to the forum! I'm trying to get an understanding of what exactly happened and when. So basically you spent the first week alone with Gracie and everything was great. Then the weekend came and your husband was suddenly home for two entire days in a row, and now she's terrified of you and everything else? Is that correct?
I'm going to finish reading her history now, I just wanted to get that answer from you as soon as I could, if you can pinpoint the moment her behavior changed it would be helpful. How did she act during the week towards your husband when he got home from work in the evenings? Did he have contact with her when he got home in the evenings, or did he not have much contact with her until the weekend started? Did her behavior change immediately on the weekend, like as soon as she realized your husband was going to be there and wasn't leaving, or was it later on or perhaps the following weekday when he was gone again and she was now again home with you only?
Cockatoos are so intelligent and so very sensitive, they are literally like a 4-5 year old child intellectually and emotionally. They have a very strong short and long-term memory, and they don't seem to ever forget much. I used to always kind of snicker when I would read an ad for someone that was rehoming their bird and they made the statement "He does better with men" or "She does not at all like men", etc. I always would kind of laugh to myself and say "No, she just doesn't like you, lol". But I have since seen a lot of examples of birds, specifically larger parrots like cockatoos and macaws that will be with a group of men and are just the sweetest birds, it didn't matter how many men would walk in the room the bird was just wonderful. Then as soon as any woman would even walk into the room the bird would turn into a terrified little monster, visibly frightened to death and biting and attacking everyone near them. So trying to understand her past life and compare this past trauma to her current situation and behavioral problems/sudden changes is the key to figuring out the who, what, when, where, and why to what can very much be a puzzle.
