What you describe is essentially what having a pet chicken is already like. Not even joking; the only difference is that it would be speaking english instead of chicken.
Admittedly, my girl is mostly trained to go on pads instead of anywhere else, and makes sure to hang her butt over the edge of the shoulder, but still.
I don't expect that the bird talking in English would change what they say, which is mostly : give me that food, monkey servant.
