Below is a photo of the completed nest box right inside the coop. It's a double-seater, which should be plenty since I only have 4 hens left. I put a hook on the bottom to hand the waterer from as well. I'm hoping the water won't get as nasty if it's hanging instead of sitting on the ground.

Below is a picture of the nearly completed nest box in my workshop. Here I'm demonstrating the hinged top and making sure the sizing is right -- notice the Blue Araucana hanging out in there trying tofigure out what's going on.

Yesterday I went in to check, and the rock was moved aside, and a nice brown egg was laying there.
Overall I would have to say I am pleased with the nest box. It took longer to build than I was hoping, but that's mostly because other things kept coming up. I could have purchased pre-built nest boxes, but what fun is that? This was a lot of fun to build, and finding my first egg in there made it all worthwhile.
