One of the women who work's at a bird store I frequent rescued a newly hatched baby Zebra finch that the parents kept pushing out of the nest.
She hand fed it. Its so cute, it comes to her when called, sits on her hand, shoulder, wherever. Obviously bonded with her as the parent.
My understanding is though that finches are for watching and enjoying!
I'm really, really tempted to get another flight cage and get finches.
