In my flock of cockatiels all but Tommy and Tammy are rescues. My daughter gave them to me because she got tired of cleaning their cage. So they would be considered a rehome.
Some were given to me from
www.rescueme.org. I paid as high as $40 to get a mutilated Phoenix when I got Flutter. The owner said he was too ugly to sell. I made arrangements to buy him sight unseen because the man called him ugly.
It is so rewarding when one of them comes out of the flock to talk to me or ask for kisses. Tommy is the only one that will step and ask for kisses every time I go in their room. That is not important to me. They are happy. If there were fewer of them I am sure they would bond to me but they all came in one year.
