Then came Spring.
That there are mice in the garage is not news. They've been leaving their droppings on the lid of the duck food container and lots of other places too. For example, there are mice droppings intermingled with crumbs of soap surrounding a little plastic container holding a bar of soap. (This soap is in the garage now. In season, the soap sits beside a rain barrel so the Duck Keeper can wash her hands without having to go inside the house.)
The soap crumbs tell us that mice can get through plastic. Still, they had not breached the tub holding the duck food. That changed. Perhaps energized by the Spring Equinox, they ramped up their efforts.
One day a hole was present in the side of the container. Employing low tech ingenuity, the Duck Keeper stuffed a rag in the hole.
The rag held, but a second hole appeared. The Duck Keeper stuffed an second rag in the second hole.
The Duck Keeper transferred the duck food into a metal container. Will there be another breach? Stay tuned.
