I have one of those zinc-lined trough planters that has seen better days. I was thinking about how to fix it up and maybe have a planter for herbs. But a better idea might be to partially fill it with dirt and top up with bedding and let them decide whether to bathe in it or lay in it.I've seen pics of plastic totes, lid on, with a side/end cut out . They get lined with something for traction, can be stacked, and set anywhere. the clay pot nests haven't been used, but i buried the bottom half in the dirt floor, thinking of the dirt box idea. I've got banana boxes too. They've never used those as nests, but the make great obstacles for littles to hide behind. I may have to make a roof for the clay pots...
Run with the tote idea and take out the bottom too....
I still have the roof issue but I have some ideas taking shape somewhere in the back of my head. When it is a little less arctic I will go out and measure.
