Ducks vs chickens, or ducks AND chickens?

I have Campbells.  They are very good egg producers.  I get an egg a day from each hen most of the year.  Even mid winter we have enough eggs from the 3 hens.  Have you ever ate a duck egg.  It is a bit different.  I like them for baking and quiche.  They are also good scrambled, but I must say I like the taste of chicken eggs better.  I would buy a few eggs before I switch birds.  They are very good bug hunters and mine pretty much stay in my yard.  The hens are loud when the quack.  

I have all 3. I keep rabbits for meat. My chickens are currently layers only, but I am planning to change to dual purpose birds. I just got my ducks, I am keeping them for meat purposes. As far as selling eggs, duck eggs can bring more money if you can find people who want them, but a lot of people just want chicken eggs. As far as noise goes, all the birds are much quieter than either my my dogs or the neighbors, especially when they all get howling/ barking at the same time.I'm not sure why this last bit is in itallics. It wasn't intentional.

Muscovy ducks can be pretty big but are quiet - quieter than chickens. However they're prone to being very broody and will start hiding thier eggs if you take them a lot to my understanding. They're best as butchering animals but certainly do lay lots of eggs each year. They're not as efficient as chickens since many chickens lay year-round and they only lay in warmer months. They also fly quite nicely though some of the males get too big to do so!

Other ducks are mallard breeds so they're ALL pretty noisy. Girls are always louder than boys. Noise level of the particular ducks VS chickens depends on the individuals involved... Except for Call Ducks which (as the name implies) make very loud calls all the time. Some breeds of chickens are known for being very loud but none are known for being quiet... That comes down to the individual bird frankly.

My ducks are more noisy than my chickens, even the rooster because they alarm more constantly...

I have both in a single pen.

(and ducks make more mess, but make up for that in personality- that is half the ducks as chickens, twice the mess)

My chickens are still chicks yet so I cannot compare. I have 14 ducks. 11 female (females are louder than males). And honestly the only time I hear them is if something startles them or scare them. Which is a few times a day- a hawk, my kids walking by them (not afraid they just get excited lol) and during meal times, first thing when we let them out of their coop and when we put them to bed are their noisiest times. Also I am their keeper- so they know my voice. I call them "hey babies! how are my babies!" and they start a ruckus. LOL But I trigger it when I talk to them in that special voice. rofl They CAN be loud but usually for a reason. Unlike dogs and boredom barking- my ducks do not the boredom or random quack. My quietest ducks are my Welsh Harlequins. Honestly they don't quack all that much. My Pekins are THE loudest and then my Buffs/Runners/Golden 300 ducks are pretty close. My Welshies are really quiet. My ducks won't start laying until September. 

I am doing ducks  AND chickens so I have an overlap. In case my hens shut the egg gate during the winter- my ducks will keep laying. And I am hoping they will all molt at different times too. Selling/giving away my excess of both.

There is a park next door to me that has kids at it all day- they are duck disturbing.

And everytime the back door opens...

Well my chicks are just little BUT i have had ducks first and have so for over a year.. ducks win the messy award, the chickens are louder! of coarse all my ducks are Muscovy so perhaps a different breed would be more comparable.

My ducks forage super well, around here my chickens would be a meal lol  The water issue for ducks creates more work and there droppings are of more significance... i think both serve a purpose, that is why i have them both.

Muscovies are very quiet, I wish I had some. 

Chickens break up the ground in gardens or lawns, ducks don't -
