I've heard that even hand raising your own bird is no guarantee the bird will bond to you... after all, it sees you as a parent, not a mate!
I believe my Casey was hand raised by a male/female couple, however she definitely preferred "momma"!!! She was incubator hatched and hand raised from day one and never pooped on her human mother. She did, however, poo on her human father! She'll accept scritches from anyone she trusts, so I don't think she has preferences.... but she is definitely used to being around women! Growing up, it was my sister, my mother and I living together. My brother in law did live with us for a while (he was visiting from his own country so didn't have a place to stay except with us) but he never really interacted with my birds (even though he is a 'bird person' - he currently doesn't own any birds).
Charlie was hand raised by a woman but he was supposedly a "mans bird" for 10 years and thus preferred men. From what I've observed, he's a "one person bird" - not a bird who has a sexual preference... and when I say he's a "one person bird" - I don't mean a bird who hates all other humans, he simply distrusts anyone who isn't "his human" until he warms up to them.... and warming up to a new person can take several weeks of frequent interactions with him. My sister can give him scritches, but the moment she talks, he freaks out! My sister and I look pretty similar in appearance and also sound pretty similar as well... which has probably resulted in a previous bird mistaking my sister for me and taking a "leap of faith" onto her! (a bird that I encouraged to jump to try and hopefully strengthen his wings and bring his confidence up - but who could not actually fly, so had to trust in me to catch him should he actually build up enough courage *TO* jump...)
