coop for both ducks and chicks

[sisterchicken]

I have 3 ducks (boys, I think) and 4 hens. They are all 8 weeks old and have been together since about 6 days old. During the day they are in a horse paddock and are currently sleeping in a kiddie pool inside our barn's tack room. I am converting an old run-in shed into a coop for all seven. I built a chicken coop in the past but never have had ducks before. I already have an automatic door from the AdorStore. (Last coop had one and I loved it.) So, here are a few questions:
1- How high off the ground can I put the door? Will ducks walk a short ramp to get into the coop?
2- Do ducks have any preferred sleeping arrangements? Right now they are sleeping on shavings but wasn't sure if something else was better.
3- Do I need to have a water supply inside coop? Since ducks are a bit messy with their water habits, I was hoping they could make it from 7 pm until sunrise without water.
4-Anything else I should know that I don't know to ask?

If it were me, I'd be thinking about separate pens for the ducks and chickens. Drakes have penises, and roosters do not. Drakes with no ducks available frequently start breeding chickens which can kill or injure the chicken hens. Good luck in resolving this.

1- My coop is a ways off of the ground and walk up their ramp fairly well, just be sure they have pegs as they slide down and use the pegs as stoppers Here’s a pic of mine. (It may take them a while to get the hang of it, it took my ducklings several months to successfully get both in and out by themselves. Sometimes still I have to pick them up and put them in for the night.)

2- Everybody has their own opinions on this but I use shavings all year long until winter when I use straw.
3- You’re so right, ducks are very messy...and it only gets worse If you plan on letting them have 24/7 access to food they must have water. I give my ducks water inside their coop but that’s just me. My coop is made of wood so doing this may result in the wood rotting faster but I still supply it anyways. Spoiled ducks.
4- Keep an eye on those boys, I’d hate to see them fighting each other during mating season.
