Over a few days some critters made it into the aquaponics shed roughed things up. First the bagged fish feed was shredded and thrown about, messy eater. The next night our friend chewed through hard plastic containers to get the remaining food. Finally, the beast came bag with indignance to smash some stacks of terracota pots and eat the kale out of the garden beds.
Lesson learned: Critter proof building, be diligent about closing up at night.
