Ducks are messy, for sure. We've only 4 atm (3g/1b) & are thinking of selling off the boy/girl to just keep two girls. We've very cold winters here -20F/-28C even, so we're not yet sure if they'll stay with the chickens or be inside the garage brooder. The extra humidity in the coop would be an issue as it'd contribute to frostbite & only ducks have that higher resistance to frost-bitten feet. Right now we're using nipple waterers for the main water supply in the coop & the ducks took to that quickly. Showed everyone else how to use them (except the dumb turkeys).
We still keep a kiddie pool in the run for them so they can swim, clean their nares, etc. In winter, if we do keep them in the coop they'll only get a thin bucket (24/7) which is just enough to dunk their heads. Oh yeah our chickens drink from their pool as well. But it's fine, since it gets emptied out every day. I only wish the turkeys would stop running into the water to steal the food bits I toss for the ducks. I don't mind them eating it, I DO mind them leaving dinosaur-sized poop in the kiddy pool though.
I love these Cayugas, they're actually pretty quiet. Not as quiet as Muscovies but they're not as loud as some of the other ducks I've seen online. The males are especially quiet (shame they don't give eggs, too

) (Here's a humble link to a vid of them if you wanted to see:

I actually almost got a flock of Bielefelder's this year. I was looking for SFH's & at the time I only saw the Biels in the area. But then I found the Barnevelders & fell in love with those too. I still have a dream of having at least one little SFH for my flock. She'd for sure be pampered. >.>
Funny about your DH. We've the same issue on naming boys. We had a BSLW roo who I joked one day about being handsome, so DH named him 'Handsome Jack' (from Borderlands 2)...and then the name stuck. So he couldn't be culled. I made my DH find a home for him, and he did...driving 4 hours to another city to give them a free rooster. Lucky bird.
I've tried setting up a "NO CUTE NAMES" policy for our farm but it's not working. So now the rule is "If you name it, you re-home it." Which seems to be working.
