Just wanted to post a little update on Lily (U2).
I took her out yesterday as she seemed to be in a fairly good mood and didn't have an "evil" look in her eyes, lol (sometimes she looks possessed or something). I took her straight over to the couch where the boyfriend and I were relaxing and watching some Stargate Atlantis episodes. She was almost a perfect little angel, well as much of an angel as she can be!
She wanted her snuggles, cuddles and hugs which made both of us quite happy as it is trying not being able to handle her most days as of late. Anyhow, she was awesome. She was only naughty when we would stop petting her, near the end she was getting kind of cranky and nipping, not hard, but that Cockatoo beak is pointy, and OUCH! lol. She also tried to get dad a few times when he was trying to be affectionate towards me, lol, poor guy. There is no room for him to share with Lily-kins! hehe. When we got back to her cage over an hour later, she leaped straight in, didn't try to struggle with me to get to the top of her cage or anything!
Today, however, I saw that look in her eyes. I took her out for a few minutes and gave her a big hug, but she immediately started shivering, and that means bad news when she starts that, so I told her "no hunny, don't start that", and put her back in her cage. She wasn't upset with me, at least I don't think so. She just went about her business in her cage!
(good thing about it is, I took her out when she was just sitting on her swing, not while she was pacing! yaay! positive reinforcement!)
I do think though, in the last discussion, some mentioned near the end perhaps cage aggression is the likely cause. I actually would not doubt that at all! I do have 2 copies of that wonderful book by Mattie, who knows why I didn't think to look in it!
LOL
Thanks for all of your help everyone! I will keep you updated.
