Here's pictures of one of my coops. I showed my dad several plans I liked and he combined the features I wanted to make this: http://www.chimeracreek.com/coop.html This was before the chickens moved in. It has great ventilation although it still needs the cupola put on the top, the roost hinges upward for easy cleaning, there's a cupboard out of reach of the chickens (shown in shelf stage in the picture), and the 6 nest boxes are easily accessed from outside the coop. 64 square feet of floor space. Its full of Swedish Flower Hens at the moment. Click on the pictures to make them bigger.
