So I don't exactly recall why we thought to purchase another bird some time later. We bought her from the same reputable pet shop as Chico. She was still a week little baby birdie when we fell in love with her and brought her home to be Chico's cage-mate. We named her ChiChi. She was periwinkle - that perfect shade somewhere in between blue and purple.
Later, we acquired another male bird named Perry from some friends of ours. So even though ChiChi would ultimately share her space with two boys, she never showed any interest. Never laid any eggs. Independent bird-woman, she was.
