I just saw your post and would be glad to do that....I've been thru your area during winter, but have never lived there, so most of my experience was in Mississippi.....I did some extensive research before settling on the KCs, but there were 3 main reasons for choosing them....they have a stronger drive than other breeds for eating snails and slugs, which are the hosts for many parasites, especially the meanigeal (sp?) worm and others that come from deer....they will begiin to lay between 17-20wks of age and will lay 300-320 eggs per year....they are very prolific layers....and their entertainment value....they actually are a cross between the Indian runner and Rouen breeds, and it is the runner side of them that makes them so entertaining.....they are a true flock bird and mainly stay together as they forage, unlike chickens that go in evey direction.
Some of the benefits that I discovered after getting them....they are absolutely relentless in chasing and eating flies, wasps, hornets, and any maggots they come across in goat litter.....I gave them some pellets....Layena non-medicated, which is what we fed the chickens....tho, they actually didn't require them, because we free ranged them in the field with the goats....they both were excellent companions and the goats never went after them and even let them roam inside their pen and house....the size of the goats, we had pygmy/boer crosses, deterred hawks....and the ducks would keep the biting flies off the goats and eat the bugs the goats stirred up as they moved thru the grass.
As a general rule, ducks lay between 5-8am in the morning and if ya pen them and let them out about 9am each morning ya can collect the eggs for the day....there will be a few that will hold their egg and release it as they move around or get in the pool and drop them there.....if they laid in a nest in the field, they would lead me to the area and just chitter away until I saw them....they were so sweet, but they didn't like to be touched or held, but would follow us everywhere and would show me where they had been that day before I would put them up for the nite....they were very routine oriented, just like the goats.
About the eggs....a duck egg is alkaline based, where a chicken egg is acid based....people that are allergic or sensitive to chicken eggs can usually eat duck eggs without issues.....the yolk is creamier and larger that a chicken egg and it also has more protien....if you bake with them, cakes and such, ya will notice a marked difference....it will be lighter, moister, and will stay that way covered with foil on the counter for atleast 4-5 days....there is a very slight difference in taste when fried or boiled, but I like it much better than chicken, but when baked there isn't any difference that any could detect.
During winters there, I would just give them water to drink each day and not be concerned about a pool....if ya close them up at nite and there isn't any food left in their area they doon't require water overnite....it is a Must if they have food to also have water....it is how they are designed to eat, the difference between a bill and a beak.....also, ducks can see in the dark, so they like to be able to have areas they can see thru around them....I kept them in a hardware cloth covered pen on the ground and used the hay waste of the goats for their bedding...deep litter method....I would stick my head out the door and listen to see if they were alerting every so often, and when they were hollaring I'd grab the rifle and check it out.....got several possums and coons that way, but never lost a duck or chicken by predator.....there were a few false alarms with them discussing who was gonna have what spot, but it was worth checking out to me.
I dumped my phone to the computer and don't have any pics on my phone now, but if ya would like, I can post some pics of their setup and some of them with the goats....just let me know and I put em on my phone and post them for ya here....I usually try to avoid doing that unless the OP asks.....if there is something else ya wish to ask I'll be more than happy to answer it for ya.....

Oh, something that is very important....if ya brood them, ya have to be sure to mix niacin or brewer's yeast with the non-medicated crumbles....it is impotant for their bone development....after they are 14-17 wks it isn't as critical and they will probably get what they need with foraging, but ya can mix some brewer's yeast with pellts every so often...once a month or so....it won't hurt them....also, if ya brood, they grow extremely fast, so depending on how many ya get....triple the space.....they are messy to brood, but once they get outside it isn't very bad at all.....and they will entertain ya on rainy days for sure!!!.....
