This is my first post here, and I'm trying to figure out a design for a new coop. All the designs I see for chicken coops show freestanding coops. I'm wondering if there's any overwhelming reason not to incorporate a coop under the same roof as some other things, in our case a garden shed and a bicycle/wheelbarrow/lawnmower/wood-shed. We currently have 9 hens, 1 rooster, and 3 ducks. They sleep in a lousy 4'x8' coop, which I'd like to replace this year. It's made of unpainted OSB, the nesting boxes are filthy and almost impossible to clean, etc. The birds are only in the coop to roost at night, occasionally lay eggs, and maybe get a snack or two. I would like to build a 6' square coop, which I think would be a better size for our flock. I'm considering incorporating it into a larger (12'x12' or 12'x16') structure, with one roof covering the coop and a potting shed on the south side (facing the house) while on the other side of the ridge beam we would have an open-sided woodshed, which would be a place to park bicycles as well. We have a small house with no existing outbuildings, no basement, and almost no attic, so we could really use some storage space, but I don't want too much because I know it will just get cluttered. I think that ventilation would be OK, even with just two sides fully open, but I'm wondering what other reasons there might be to make the coop a separate structure, or not. I anticipate keeping about a dozen hens on average, and I think that 36 square feet is about right for that, considering that they have nearly infinite range outdoors and are only kept in by the weather a couple of days in the winter, if that. Thanks!
