BYC some help please. I'm just starting and I picked up a second hand Eglu Classic. My Classic and Run (stock photo here http://www.omlet.us/products_services/products_services.php?view=Eglu%20Classic) are on a wooden deck above my garage. Its the best I could do in the dense area of Chicago. I can take an old drawer and fill with sand, etc. for the chickens to dust and scratch in. My bigger concern is...the run is just on the wooden deck. Any suggestions on trays or containers or something that I would hold whatever I put down (wood chips? sand?) for the chickens to walk around in/poop in (something that I would be changing every once in a while) I don't have a lot of room to work with. Thanks much!
