This coop is connected by a wire tunnel to a large run next door in a neighbor's yard. The owner is reflected in the glass. The neighbor also has a coop connected to the run.
It was at this site that I didn't hear about any raccoon problems. One of the owners opined that there is so much cat and dog food in the neighborhood that the raccoons have gotten lazy. After all, catching a chicken requires some work. All the other coop owners I talked to had a raccoon story.
