Cayuga ducks in general are quieter than other breeds, though females are louder than males. Females have a loud quaking sound and males have more of a wheezing sound.
Yes, they can be bred together, but obviously, some traits from each breed would come out in the eggs (or the ducklings). This would create a crossbreed between the Pekin and the Cayuga, the same goes for any other two breeds of ducks bred together, e.g. Mallards and Muscovies, or Pekins and Muscovies. The Cayuga itself I believe is a crossbreed.
cayuga ducks lay approximately 100-150 eggs per year if properly cared for.
6 months.
For showmanship, it's a disqualification for a Cayuga duck to have white on any of the plumage. Cayuga ducks are supposed to be all black and be iridescent beetle green when in the correct lighting, though it's not uncommon for females to have white on their chest.

Female ducks are called "Hens" and male ducks are called "Drakes"
Female ducks are called "Hens" and male ducks are called "Drakes"
They rubb their heads on other male or female ducks (depending on bi or straight)
If you mean a heart, yes. All ducks do.
They are a giant version of mallards. They are more calm and relaxed. I suggest Rouen Ducks instead of mallards, because Rouen ducks don't fly away.
Neither male ducks are called "drakes", female ducks are simply called "ducks"
