Great job. I do have a few suggestions, though. Love the nest boxes, but Silkies are very broody types. If you were to set the boxes on the ground, or floor, and perhaps make a frame to hold them in place, the Silkies would love it. Also, if they aren`t fastened they could be easily moved with broody in place to a secure maternity area or small pen, for privacy, which is very important for broodies. The other suggestions I have concerns the run. PT would be good for the bottom plates. Hardware cloth is much superior to chicken wire, and an apron around the bottom for security is usually a good thing. You might want to build it high enough to stand up in, for your own convenience. You`re well on your way. Great job..........Pop
