Chicken coop is 12 1/2 X 8 & 1/2 ft with a notched out area (I call it their phone booth) that is 4ft X 5ft. Their phone booth area has a staggered roost type area and that's where the majority of the chickens roost at night. Outdoor attached run is 10 X 10. Large area is 50 X 70. Then the ducks have a pen about 12 X 7 with their open area of 50 X 25. We put up fishing line across the open area so we have no escapees. It's worked great so far. Our watering system is great, my husband designed it. 55 gallon drum with hose and water trough and float system. We opened up a small area on the duck pen so the ducks have access to the chicken water, but not too much access so they can't slop it around a make a huge mess.
For winter we put a water de-icer in the drum, wind a thermal heating cord around the water hose and then put a brooder light above the float. It makes it so we only have to fill up the drum a few times during the winter. I love this!
So far the entire set up works great. We've tweaked it quite a few times but right now it's great. I toss their mulch around every couple days and clean out the trough every few days (ducks still dirty it up). Because the pens are open but not drafty, the temps are not too horrible in the winter and there is rarely any bad smells ever. Actually I'm amazed at just how nice their areas do smell. I hate stinky smells but their pens just smell like feed and mulch. Guess it's cause they spend so much time outside and because they are more open.
