Ok, since I seem to be getting useful comments, and not comments like take my advice and return it to the seller, I can share my story.
My wife and I have a new 5 month old U2 that at least right now, is perfect. The only screaming is her happy posturing screaming a coup,e times a day, and we kind of enjoy that. Lets us know she is happy. We have some experience with birds, but they are smaller birds. 3 Quakers, a GCC and a Cherry Headed Conure.i say the U2 is a she, but we are waiting for the sexing to come back. She is separated from the other birds right now. We have a pretty decent size cage for her 40"w, 30"D and over 6' tall. I'll have to get pics up. She has tons of space, lots of toys, and a bunch of spare toys to be rotated in and out. She is eating pellets and large bird fruit and nut mix. She has been getting evening baby formula feelings, but tonight she only took half as much. We weigh her before and after these feelings and we are keeping a record of her weights. We are trying to help build her confidence and give her love and cuddle time without being to much. As of right now, she plays independently on the playgym or boing for long periods, but sometimes she gets the urge to fly to one of us. I know things can change, but I am just trying to know as much as possible to work towards success. My Cherry Head came to me at a year old and very fearful. It's taken 2 years, but he has really come around for me. I guess I am looking for encouragement, and hope that there are success stories out there instead of all the horror stories I am reading.
