While this is not technically our first coop, it is the first one we've built from scratch. My wife and I purchased a small store bought coop last summer after her spur-of-the-moment purchase of 4 chicks. We started framing the "real" coop last fall but were not able to complete it before winter. Now that the MN winter is (hopefully) past, we have been working on it again in recent weeks. I have an idea of what we'd like but I'm interested in feedback from the chicken "experts" 
We live in the country and predators include opossums, raccoons, and coyotes. We let the chickens roam the property during the day and lock them in the coop at night. We did lose one to an opossum one night when the store bought coop was shut but not latched well enough. Snakes are not a concern where we live. There are some small mice which are "mostly" kept at bay by our cats.
Here are a couple pictures of the 8' x 12' coop we are building.
I need to fix a couple rafters on the north (left) side of the roof to lower it a half inch or so and get the roof level. The frame being out in the elements for 6 months and stopping/starting on the project as time allows hasn't done us any favors. We have 1/2" hardware cloth we will be putting on all areas that don't currently have siding, with a door on the north (left) wall. The south side will have a "box" between the 2 southernmost 4x4's from the bottom of the siding all the way to the roof which will be insulated. There will be a ramp leading up to the "box" and nesting boxes built into the "box" on the side to the center of the building. The hardware cloth will extend up behind the exterior siding about 6" and we will add wood trim over where the hardware cloth attaches to the 2x4's and 4x4's on the exterior. Should be near impossible for anything to break into. Still debating on what to do at ground level both inside the coop and outside to prevent creatures from digging.
Suggestions are definitely welcome!
