I have other neighbors, too.
These are the chicken coops along the side fence of Court 3. The chickens are right across the "street" from me.
The more I study this installation, the more convinced I am that it was originally constructed as a kennel for the guests' dogs. And in fact the left half could still serve that purpose. However, a chicken wire ceiling has been installed over the right half, and the chickens have that half now.
Both Texas and México are very chicken friendly places.
