The coop is a tool shed with a chicken door and window added, and the run is made from dog kennel panels. We enlarged the run just this past weekend as I've seem to come down with wantmorechickensitis. It was half the size it is now. On a side note I killed a baby rattlesnake outside the coop this afternoon. I cut off its head and gave the body to my hens. They quickly tore it apart and ate it. They can be viscious when the want to be. Hee hee.
