Very nice Opa and thanks for sharing this with us. I love it! Do you put anything on top of the astroturf? Do the hens use the boxes without any "bedding" in there? My coop is a combination chicken coop and goat barn with a 4' wide access area between the two spaces. This would be a great place to have the discharge end of your design. I could just walk into the little barn and gather the eggs. Hmmmm pretty cool.
