I have 3 cayuga ducks right now, 1 male 2 females. They are about 7 1/2 months old now and still have not layed an egg. They seem to have reached their full size which seems a bit small to me so I'm thinking about adding a new breed to the flock for increased meat production. My cayugas are extremely quiet and only quack when separated so they seem to be working volume wise, but in my research I haven't found a larger duck breed that is also relatively quiet. The ideal breed i would go with are silver appleyards but they have a reputation for being on the more noisy side. The only breed I found that is large and also quiet are Muscovys but they only seem to be seasonal layers and not as effective for egg laying purposes. Any suggestions for a bigger bird that might also lay a little more efficiently but still stays quiet would be appreciated!
