I'll take some pictures of mine in the garage when I have a day off work so I can take them with some daylight. My set up isn't fancy though, just stack cages with coated wire, all coated not just the floors. They stay pretty clean that way but there is more waste to the feed. I have different feeders, some hanging type, some are like the rabbit feeders and some are just feeders that attach to the wire walls. All are fairly wasteful but I bought some rubber door mats, the $3 kind with the little nubs on one side. I cut them in half and put them nub side up, under the feeders. The feed scratched out gets caught in the nubs and has a second chance at being eaten. It does get dirty but it's easy to pull out and hose off when I clean the pans under the cages. The water bottles are easy, clean and hold enough for 2 days for a pair and a trio usually has a little left at the end of the day so I fill some of the bottles almost every day. I still prefer them to open water dishes that may hold more water but is dirty pretty quickly after they've been cleaned and filled.
I hope to have some pens set up next summer for a couple of small flocks to be on the grass part of the day. I'm looking into a couple of small green house frames that I can cover with welded wire, even the bottom. It should be large enough that I can build a small, covered roost area and a couple of nest boxes inside and part of the top will have shade cloth or some other type of cover for a sun/rain shade. I'd like to have 2 roosters that will get along in each and enough hens to keep them occupied. I want to make them like a chicken tractor with wheels on one end so the whole thing can be tipped and pulled to a fresh part of the yard with my 4 wheeler or just pull by hand if it's not too heavy. I might make one for a grow out pen too. I figure I'm going to need to make a couple of cages for the ones I plan to show too. Plenty of room and a solid floor and bedding that will help to protect the feathers. I have some big plans for next spring.
Winter time is mostly just keeping them safe, warm enough and a place where I can spend a lot of time playing with them so inside the garage is working fine right now. It's dark when I leave for work and dark when I get home so a draft free, lit up area to play with them after dinner is so much more relaxing than watching Tv
