Comment on the chickens and diapers. Just like with babies and the elderly, a diaper can be terrible. Pressure sores, rub spots, if not changed and cleaned frequently enough problems from the fecal matter coming into contact with the skin, etc.
Frankly, I am skeptical about how it could affect the health of the bird.
I raise silkies. I show silkies. My silkies are tame, well handled, and there are those that I truly adore..... but they are not well suited for housepets. The featherdust alone would drive me nuts. Not to mention they love nothing better than their dust baths in clean pine shavings, which flings shavings and dust everywhere. I can only imagine the mess this would make inside a house.
