Our coop is smaller than yours, (6 x 8, with 8 foot ceiling) but we planned it for minimal fuss and maintenance.
Our food bins are two "small pig feeders" from
Tractor Supply mounted on the wall. No spillage, open at the top for easy filling, and take up almost no room. Our feed is in a plastic step on lid trash can in the coop that holds a full bag of feed-- couldn't be easier.
We have two one gallon waterers, and we just fill one and bring it out each day when we check on the girls, and bring the other one in to be rinsed and refilled. Currently we have a three gallon waterer in the run that gets refilled a couple times a week, but honestly, they could probably do just fine without it. We happened to have it, so we use it.
We are using the deep litter method, so cleaning is minimal. We have three bricks of shavings on the floor, and we just toss them with a pitchfork a couple times a week. Our hens moved into the coop two months ago as 10 day olds, and we haven't had to change out the litter or do any other coop cleaning yet.
It seems, at least in our limited experience, as long as the litter and waste is dry, and the coop is well ventilated, it doesn't smell. Of course, our girls have a decent sized run that they're in and out of all day, so that probably helps, too.
