The key is good ventilation and moisture control. 1) If you have waterers inside your coop, spot clean all water spills AT LEAST once a day and minimize them by placing waterers off the floor/bedding (on a concrete block, wood stand, etc.) or hanging them in a way the chickens can't tip them. 2) make sure there is sufficient air flow to dry out the poo, and turn your bedding regularly (for deep litter method). If you throw down a little bit of scratch grains your birds will turn it for you. BUT ... 3) if your feeder is in your coop, don't let processed feed build up in the bedding. It's absorbent and will quickly spoil if it gets moist. I keep a "scratch tray" around my feeder. It's just a square of ply with 1X4 sides sized about twice as big around as my feeder, but it's been a great food saver and odor eliminator. Any feed the chickens drop out of the feeder end up on the ply and gets "scratched" up. I can scrape up any that isn't (along with any other "deposits" that end up there) every day when I brush down the roosts and clean the poop board, and that brings up 4) put a poop board under your roosts! Even if it's just bare plywood, it still makes cleaning - and thus odor control - so much easier. Many people cover theirs with linoleum. I put shallow sides on mine and keep sand in it. I can scoop the poop into my cleaning bucket in seconds, and just add a bit of sand when necessary. Saves time, labor, and money, and keeps odors down.
Once what's in the coop goes out to the compost, the same principles apply - good ventilation and moisture control. If your compost pile is not too large, ventilation involves turning the pile with a rake or pitchfork often. I have several piles around the farm, each at a different stage of "cooking". Older piles are too big to turn to their base, so I insert pvc pipes with holes tapped into them through the piles at about a 45 degree angle downward from the sides to the center. Air flows down the pipes and keeps the aerobic activity going. As for moisture control, that's a siting issue. Don't put your compost where it's going to stand in water when it rains, and in times of excessive rain you may even want to throw a tarp over the pile (but stake the bottom edge out from the pile to allow ventilation - I keep mine covered and add water with a hose mister when things get too dry). That said, if you can devise a way to collect the moisture the pile produces as it cooks, that's the "mother load"! Dilute this "black gold" in water and feed it to your garden for some of the best production you've ever seen. I built up shallow mounds of hard-packed clay soil under my piles, with drainage channels formed into their outer edges. I lined these with plastic and directed the liquid drainage into partially sunken 5 gallon buckets with rain shields over them. Once a bucket is about half full, I can lift it out, add water, and feed the garden. It's a way to reap some benefits from your compost even before it's ready to add to the soil.
Anyway, didn't mean for this to run this long. Hope you find at least some of it useful. Best of luck with the new chooks.
