Does anyone know of a breed that...

Muscovies. Hardly make a sound as far as I can tell.

They get so big and fat that they can't fly. More to the point, train them to come home every evening and they won't fly far.

They can fly. The hens fly very well, I thought my big drake Virgil(18lbs) couldn't fly any more he is so huge. Turns out he just choses not to fly very often, He took an amazing flight just the other day. He looked a little weighted down and didn't get much higher than 6feet, BUT he flew. I suggest Muscovies as well but clip or pinion as they can and do fly.
