I rebuilt my coop. I will post pics next week after I clean up a little, but I had to share this . I made a rather large POOP TRAY 4x8 plywood with 2x3 edges and tarp on bottom . Two handles to pull it out to clean, but it was heavy so I got about 12 of these for about $1.00 each and it pulls out like a dream. had to share http://www.ebay.com/itm/Roller-Ball...783?pt=LH_DefaultDomain_0&hash=item51c9fea11f The also have these at Harbour Freight for cheap.
