I saw AndreaGS's beautiful hutch and decided that something similar would work very well for us here. Here's what I've got so far. I put this all together in about 3.5 hours last night, with the exception of the roofing. Don't mind the overhanging wood on the roof. I'm going to trim those three back to the wood panel. The roofing is probably a little sloppy... I've never done roofing before. That stuff is HEAVY. I added four rails to each level for the poop trays to slide in and out on. I need to frame in some doors for what will be the wire cage areas on the right, and box in the cubes on the left hand side for shelter. I originally thought that perhaps I made these too big, but then I realized were in Michigan and Andrea is in California. I'm betting our guys might need a little extra indoor space, so I'm leaving them as-is. The exact dimensions of each quail cage on this double decker are 2' 3" deep, 4' 3" wide and 15" tall.
