so you are saying that I can raise meat ducks instead of broilers? Hmm. I am also a backyarder that tried barnyard surprise hatching this year. The cockerels made it to 12 weeks before becoming a nuisance. I could have pushed my luck, but had 10 of them starting to compete. Took out the loud ones and the quiet ones filled the void.
Pekins or Muscovies? I heard Muscovies only hiss, but they will fly. Guess I will research Pekins. I'm raising quail at the moment, but love wild duck. Chicken is nice, quail is closer, but duck!
A lost Rouen stayed with us for a couple of weeks. Since she was so friendly, the family decided she was a pet. WE rehomed her.

In short, she was loud and constantly calling. Pekins are quieter? You have piqued my interest.
