cockatiel looks like plucked chicken!

Help! My F Lutino tiel is 9 yrs old. I hand fed her from day 1 (parents rejected) She always cared about her looks, but the past year I put her with a younger M whiteface tiel. They seem to have a love hate relationship. She started pulling out her feathers, under her armpits, base of butt, etc. 2 days ago I found her wing bloody, she had been chewing it up. I have removed her from the male.

She seems to be itchy all over. You can't tell to much with her wings down. When she raises her wings she has pulled out feathers down both sides and under wings.

Please what is wrong? Susan
