Thanks for sharing Walt. Very interesting.Once ducks are grown I think they are a whole lot easier to raise and keep than chickens. I have 500 birds here and half are waterfowl. Some female ducks can be noisy, but usually the larger the duck the less noise it makes., I have about 50 Runner ducks here and they are champion layers and I don't think they are noisy at all. Sometimes during breeding season they make noise, but they are not like the bantam ducks. There are very few chickens that will lay like Runner ducks do and the eggs are bigger.. Muscovys are quite, but they only lay a few clutches a year and don't lay all year like Runner ducks do.
In addition they are not dropping dead all the time like the chickens I read about here on BYC. A young duck has to be pretty mcuh hit by a truck to die before they are 10. I have ducks here over 10 years old that are laying like champs.....all year long. If you set your yard up right, ducks are easy keepers and not all that messy when adults. If you cram them in an 8 X 10 cage they will be messy.....if they have room they will not be messy.
