(As I don't have ducks this review is mainly focused on the chicken coop.)
The tones of the recycled wood gives these coops a beautiful, rustic effect while saving a lot of money and saving wood from being tossed out. So thumbs up on that!
The layout appears to be fairly functional as well for a small flock, however I am concerned about ventilation with a build like this... even if those side windows are wire mesh instead of glass, it's still a minimal amount of ventilation. I'd rather see some slots left open towards the roofline as well, or maybe a small window on another side, to capture some cross breeze.
The roof is also an issue since snowfall was mentioned. In an area with very little or no precipitation a flat roof might be something you can get away with, but any decent rainfall or snow will be problematic on a flat roof. The slanted roof seen on the duck coop is a better option.
