I think this is a great idea! I love the recycling aspect of it. You may want to put the nest boxes directly on the floor of your coop and not above the roost to keep the chickens from sleeping in and making a mess in the boxes. Chickens like to roost as high as possible (except for silkies...
I am looking forward to this contest! I've often thought chickens must molt in the Fall-just so they can create their own unique Halloween costume. Molting chickens make great chicken skeletons, zombies and dinosaurs.
This summer I used sand in the run and also inside the coop. I have a poop board under the roost in the coop that I sprinkle with sweet pdz ( in the old parmesan cheese container) and scrape off daily. This system has been easy and has kept things clean and dry. This winter I am considering...
Your coop is similar to ours, but I like your roof much better! Regular shingles made our coop so heavy. I also like the way your hardware cloth and metal roof add extra ventilation. I am sure your girls will enjoy their great home!
In the interest of saving space in our run we decided to place a small roosting perch outside the pop door instead of a ramp. The chickens easily jump up and down a few feet and they also like to use the perch to keep on eye on the back yard.
We put the roost bar in front on the window. Since these pictures were taken we've added a poop board under the roost and change to all sand inside instead of pine shavings. (so much easier!) The nest box is open in a corner and the girls us it without problems. Food and water are kept...
I just switched to using construction grade sand inside the coop. For me it has been much easier and cleaner than using pine shavings. I sprinkle the poop board with some Sweet PDZ daily. (I keep some inside the coop in an old parmessan cheese container) I use a cat litter scoop to clean up...
