Hi,
This is my first year with chickens (6).  They have a 6 x 6 x 6 foot coop area, and an attached outdoor totally enclosed run, 6 x 20' so they spend just the evenings inside.  They mostly poop under the roosting area.  I clean up the visible poop every day, first thing in the morning before breakfast, using rubber gloves and an old newspaper plastic bag, like cleaning out a kitty litter box.  I use shavings, about 6 inches thick, and sprinkle/spread fresh shavings over the old every couple of days.  This is probably a variation in the deep litter method, as I will probably change the whole litter next summer.  There's no smell at all if I keep up with it.  I've found that if I leave a heat lamp on in the night, the light keeps them more awake and they move around more, therefore spreading out the poop, so...I'm going to limit the heat lamp to just a few hours in the wee hours of the morning to take the chill off (I live in Colorado) and let them sleep longer.  Hopefully the poop will then be more concentrated under the roost area.  They don't poop in the nest boxes--I have three.
